Question 4:

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.

4.99+4.99+3.99+19.99=$33.96

0.12x33.96=$4.08

4.08+33.96=$38.04

Question 6:

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?

85.00÷2=$42.50

42.50÷10=$4.25

42.50-4.25=$38.25

Question 13:

What is the total cost for four tires that

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

1.5% environment tax?

85.00x4=$340

0.065x340=$22.10

22.10+340=$362.10
