Question

The local electronics store is holding a 20%-off sale on all its products. Maria selects 2 CDS at the original price of 16.99 each. What is the price of the two CDS after the 20% discount?

Answer 1

2*$16.99=$33.98

20% off

20%*$33.98=0.2*$33.98=$6.796=$6.80 off

$33.98-$6.80=$27.18, the price of the CDs after the discount

another  way of solving this...

if there is a 20% discount that means that Maria pays only 80% of the $33.98(100%-20%=80%)

80%*$33.98=0.8*$33.98=$27.184=$27.18 again
