Question

A sign above a basket of DVD reads "3 for $17." Kellen decides to buy 6 DVDs and use a coupon for 25% off. If sales tax is 6%, what will he pay in total?

Answer 1

The pay in total will be:

since 3 cost $17then 6 will cost 2(17)=$34

then we apply the coupon for 25% off, obtainning 34-0.25(34)=$25.5

now we add the taxes, 25.5+0.06(25.5)=$27.03

Then the final price will be 27.03 dollars
