Question

A shopper at a clearance sale is pleased to discover some cookie jars on sale for $19 each. The original price tags read $20. What is the discount percentage?

Write your answer using a percent sign (%).

Answer 1

Answer: 5%

Explanation:

1. 20-19= 1

2.
`(1)/(20)= (x)/(100)` Part/whole = Percent (X) /100

3. Cross multiply: 100 = 20x

4. Divide to isolate the variable:
`(100)/(20) = (20x)/(20)`

5. X=5

So the discount percentage is 5%.
