Karra's Percent scribepost

Question 1.

Chris purchased the following items:
  • 2 Binders for $4.99 each
  • 1 math set for $3.99
  • a backpack for $19.99

find the total cost including 5% GST and 7% PST.

My answer is ..

Question 2.

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?

My answer is ..

Question 3

Describe 2 ways you could calculate the total tax of an item?

In my opinion i would use a ratio table. My other way is by using a formula where you multiply the original number by 100 or more.
