Question

Mary bought a pair of jeans on sale for 25% off. The original price for jeans was $79. What was the sale price before tax? Explain how you got the answer

Answer 1

Answer:  $59.25

========================================================

Explanation:

There are two approaches

Method 1

25% of 79 = 0.25*79 = 19.75

Mary saves $19.75 and the price before tax is 79 - 19.75 = 59.25

-----------------------------

Method 2

She saves 25% so she must pay the remaining 75%

75% of 79 = 0.75*79 = 59.25

This is a slight shortcut, and it's very useful when it comes to chaining multiple discounts together.
