A backpack that regularly costs $72 is marked down by 30 percent. What is the sale price?

Correct answer to question 146 (Arithmetic Reasoning): $50.40

Method

A 30 percent discount takes off 0.30 x 72 = $21.60, so the sale price is 72 - 21.60 = $50.40. Reporting $21.60 alone gives only the savings, not the price paid.
