### Scribepost for February 2 2010

Today in class, we filled in 4.4 in our foldable and we some questions in our textbook.
I was assigned number 5 and 9.
5. Ravi purchased 3 DVDs for \$19.99 each.
Find the total cost for the DVDs including
5% GST and 6% PST

I rounded \$19.99 to \$20.00 because it was an easier number to work with. They I multiplied \$20.00 by 3 because Ravi bought 3 DVDs.

I combined 5% and 6% and made 11% in tax

First I found 10 percent by dividing by 10.

Then I divided by 10 again to get 1 percent.

Finally I added 1% and 10% and got 11%

The final price of the DVDs would be \$66.60
9. Arjay was thinking of buying a car worth
\$23 000, but delayed purchasing the car
for a year. During that year, the cost of the
car increased by 3.2%.

a) What was the price of the car when
Arjay purchased it?

First I found 10 percent by dividing by 10.
Then I found 1 % by divding by 10 again.
Finally I divided by 10 one more time to get 0.1% and times by 32 to get 3.2%
The final price would be \$23000.00 + \$736.00=
\$23,736.00

b) What was the total cost of the car
including 5% GST and 5% PST?
5% + 5% = 10%
To get 10% I divided 100 by 10
The final price with all the taxes and the current price would be \$26,036.00
