Damian H's percent scibe

Hello if anyone reads this my job was to make a scribe about 3 question from pages 148-153 or I would fail grade 8 math.

I picked question 4, 10, and 13 on page 148-149.
{Q4} The question is find the total cost including 5% GST and 7% PST on

• 2 Binders at $4.99 each
• 1 Math set for $3.99 
• A backpack for $19.99

To find the answer I added tax on all the items individually then added all the items+ tax on each item together which gave me the answer $38.04.

• 2 Binders at $4.99 each x 1.12(tax) = $5.5888

+

• 1 Math set for $3.99 x 1.12(tax) = $4.4688

+

• A backpack for $19.99 x 1.12(tax) = $22.3888

                                                                                             
=                                       $38.04

  

                                         $5.5888

Question 4 - Page 150
How many hundred grids are needed to show each of the percents.
A)101% = 2 hundred grids
B)589% = 6 hundred grids
C)1450% = 15 hundred grids

Question 4 Pg 148

Chris purchased the following items:

-2 binders for $4.99

-1 math set for $3.99

-a backpack for 19.99

Find the total cost including 5% GST and 7% PST.

What I did was that I added all 3 of them to make $33.96.

I also added 5% GST and 7% PST to make 12%

so I multiplied $33.96 x 1.12 = 38.04

Question 10 Pg 149

What is the total cost for four tires that sell for $85 each, plus 5% GST and 1.5% environment tax.

I found the total for the four tires which was $340.
Then I found 1% of 340 = 3.40.
3.40 x 6 = $20.40
0.5% = 1.70
1.70 + 20.40= $22.10
340 + 22.10 = $362.10

The total for the four tires is $362.10.

Thanks for reading my scribe!

Question 1.

Chris purchased the following items:
-2 binders for $4.99
-1 math set for $3.99
-a backpack for 19.99
Find the total cost including 5% GST and 7% PST.

First off , I added the prices together and multiped 4.99 by 2 becuase it says 2 binders at 4.99 each .

All these items came up to $33.96

Then i added the GST and the PST which have me 12 % .


Question 2

How many hundred grids are needed to show each of the following percents?
101% equals 2 hundred grids
589% equals 6 hundred grids
1450% equals 15 hundred grids

Question 3.

Describe 2 ways you could calculate the total tax of an item?

I would use a ratio table and my other way is using a formula where you multiply the original number by a percent greater than 100.

Draw a diogram to show how you could represesnt the cost of an item including with or without tax.

Question #1

$ | %
100 | 100
106 | 106

The item is $100 and if the tax is $6 it would be $106 so it is
$100 x 1.06 = $106

Question #3

Kyle says that a population increases of 15% on year follows by a increase of 10% the next year is the same as a population increases of %25 over two years. Is Kyle correct? Explain your reasoning.

Kyle is not correct the population would be greater if it increased by 15% then 10% If it increased 20% it would be less.
Increased by 15 then 10

Starts at 1000.

Chris purchased the following items:
2 Binders for $4.99 each
1 math set for $3.99
a backpack for $19.99
find the toal cost inculding 5% GST and 7% PST.
So i started by adding all the subtotals together
$4.99+$4.99+$3.99+$19.99= $33.96
5%+7%= 12%
$33.96x 1.12= $38.04


Question 4 (page 150)
How many hundred grids are needed to show each of the following percents?
A) 101% = 2 hundred grids
B) 589% = 6 hundred grids
C) 1450% = 15 hundred grids

Question 10
What is the cost for four tires that sell for 85$ each, plus 5% GST and a 1.5 environmental tax?
first I found the total of 4 tires, which is $340.
Then I found the taxes by doing this:
$340 x 1.065 = ?

Question #4 (page 148)

Chris purchased the following items:

• 2 binders at $4.99 each

• 1 math set for $3.99

• a backpack for $19.99

Find the total cost including 5% GST

and 7% PST.

What I did:

$4.99 x 2 = $9.98

$9.98 + $3.99 = $13.97

$13.97 + $19.99 = $33.96

Now you have to add the tax which was 12% when you add 7% PST and 5% GST together.

The total cost would now be $38.04 with the tax.

Question #6 (page 148)

A store discounted items by 50% off the

original price one week. The following

week an additional 10% was taken off the

already reduced price. The regular price

of a CD player was $85.00. What is the

reduced price in the second week?

What I did:

Regular price = $85.00

50% off the original price one week

additional 10% after reduced price from the first week

After finding 10% of $42.50:

$42.50 - $4.25 = $38.25

The reduced price after the second week is $38.25.

Question #10 (page 149)

What is the total cost for four tires that

sell for $85 each, plus 5% GST and a

1.5% environment tax?

What I did:

each tire = $85

tax = 6.5 % (5% + 1.5% = 6.5%)

$85 x 4 = $340

The total cost for 4 tires would be $362.10 with tax.

Total Cost = $100.79

C) Total Tax = $4.80
Total Cost = $44.79

D) Total Tax = $22.80
Total Cost = $212.79

To get the total cost I multiplied the original price by 1.12 and got the answer.
To get the total tax I subtracted the total cost from the price and got the tax.

Scribepost Questions 5 and 8.

For scribe post we had to pick 3 questions so i decided to pick numbers 8, and 6.

6.
For number 6 we had to find out the discount price of the second week. the fist week it is 50% off. the second week is 10% off of the first weeks discount. your starting price is $85.

So first i went:

50% off of $85 =$42.50
To get the answer I just went: 85 /2 = 42.5

so now that i have my price of $42.50 i can just take 10% off of that witch equals = $34

Another way i found the answer is I just found 40% of $85.

85/100= o.85 x 40 = $34

The total price they had to pay is $34.

Scribepost for Feb. 2

Questions 7 & 11

7. A herd of 100 caribou was moved to a new location. The population increased by 10% the first year and then increased by 20% the second year.

A. Find the population after the second year.

- 100/10 = 10%
100+10 = 110
110/10 = 11x2 = 22
22 = 20%110+22 = 132

There will be a population of 132 caribous.

B. Explain why there was not a 30% increase in population over the two years.

The increase is not 30% because the 20% increase is based on the population after 10% increase in the first year.

11. A student is awarded a $1000 scholarship and places it in an account that pays 3% simple interest per year.

A. What is the total value of the scholarship amount at the end of the second year?

- 1000/10 = 100
100/10 = 10
10x3 = 30
30 = 3 %
1000+30 = $1030
1030/10 = 103
103/10 = 10.30
10.30x3 = 30.90
30.90 = 3 %
1030+30.90 = $1060.90

The total value of the scholarship is $1060.90

B. What is the single percent increase in value of the scholarship after two years?

- 3% = 30
30+3% = 30.90
60.90/10 = 6.09%

The single percent increase is 6.09%

Binesi's Scribepost for February 1 2010

For our foldable we had to copy down the key ideas:

Percents can be combined by adding to solve problems. 5% + 7% = 12%

- To calculate the increase in a number,

-You can add the combined percent

amount to the original number.

12% of 100 = 0.12 × 100 = 12

100 + 12 = 112

-You can multiply the original number

by a single percent greater than 100.

112% of 100 = 1.12 × 100

= 112

- Percents of percents can be used to determine amounts that result from

consecutive percent increases or decreases.

Then we had to do the 2 show you know questions on our foldables.

A backpack costs $35. Use the method of your choice to find the

total cost of the backpack if GST is 5% and PST is 6%. Use another

method to check your work.

First you have to add the taxes together (5+6=11)

Percent-100/100=1

Dollars- 35/100=0.35

Percent- 1x11=11

Dollars- 0.35x11=3.85

Then all you have to do is add $3.85 to $35 to get $38.85

The second way I did this was: 1.11x35=38.85

The second show you know:

What is the final sale price at each store? Which is a better buy?

Explain your thinking.

Store A: 50% off one day only

Store B: 25% off one day followed by 25% off the reduced price the

second day

I'm pretty sure you use the $200 hockey mask example.

Store A

Percent-100/2=50

Dollars- 200/2=100

Store B 1st day

Percent-100/4=25

Dollars- 200/4=50

Store B 2nd day

0.25x50=12.50

50-12.50=37.50

37.50+200=237.50

I don't know if I'm right, so correct me if I'm wrong.

Scribepost for February 2, 2010

Today in class, we had a couple of assignments to do. We had to fill in our foldables and do the odd questions in our textbook.
Here are questions 1 and 3.

#1:
Draw a diagram to show how you could represent the cost of a $100 item with and without tax.

The diagram I drew was a ratio table. With a ratio table, you would be able to see how much the item costs and how much you would pay with the tax.



#3:
Kyle says that a population increase of 15% one year followed by an increase of 10% the next year is the same as a population increase of 25% over two years. Is Kyle correct? Explain your reasoning.

Kyle is incorrect. The population increasing by 15% and then by 10% would be a greater population than if it just increased by 25% altogether.

I got my answer using a ratio table:
