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 13:

sell for $85 each, plus 5% GST and a
1.5% environment tax?

85.00x4=$340
