Question

Staples has a calculator that is regularly priced $20 and is now on sale for 40% off. Brain has a coupon for 10% off anything in the store. What is the sale price of the calculator?

Answer 1

[(20)(.6)](.9)

The original price is $20, and the sale is 40% off, so that leaves 60% of the original, or .6

Brian's extra 10% off leaves 90% of this value, or .9

Multiply to solve
$12 is the sale price of the calculator and
$10.80 is the sale price of the calculator with the extra 10% off
