Question

Find the sale price if a customer buys a $40 shirt
that is 20% off.

Answer 1

If the shirt was bought at $40 when it was 20% off then the original should be $50

Answer 2

$8

Explanation:

To find 10% of a number, move the decimal point over by one. Since the number is a whole the decimal point looks like this

$40.00

Move it once to get 10% which is 4. Then multiply it by 2 to get 20%.
