Question 5 (page 148)
Ravi purchased 3 DVD's for 19.99 each. Find the total cost for the DVD's include 5% GST and 6% PST.

3 dvd's= 19.99 x 3 =59.97
tax = 11% 59.97 x 0.11= 6.6
11% = 6.6
59.97+6.6= $67.6 3 DVD's plus tax is total to $67.6

Question 6

First week
50% off of $85.oo is 85.00 x 0.50 =$42.5
