Noel's Percent Scribepost

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.


Question # 4
How many hundred grids are needed to show each of the following percents?

c)1450%= 15 squares


Question 4 Pg 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.2 binders $9.98 + 1 math set $3.99 + a backpack $19.99= $33.96

Now you have to find the added taxes which is 12%.
I found 10% first which was $3.40.
Then I found 1% which was $0.34.
0.34 x 2 = 0.68
3.40 +0.68 = 4.08
33.96 + 4.08 = $38.04
