Question

Laura bought a pair of shoes for 20$. The shoes were on sale for 15% off, and she also used a coupon for an extra 20% off. Before sales tax was applied, how much did Laura pay for the shoes?

Answer 1

$13.60 before sales tax

Explanation:

$20 x .85 (aka 15% off) = $17

then

$17 x .80 (aka 20% off) = $13.60
