Camille uses a 20% off coupon when buying a sweater that costs \(\$47.99\). If she also pays 6% sales tax on the purchase, how much does she pay?

\(\$40.69\)

Explanation

First, compute the price of the sweater after the discount:
Discounted price of the sweater \(=(100 \%-20 \%)(47.99 \text { USD })=80 \%(47.99 \text { USD })=0.80(47.99 \text { USD })=38.39 \text { USD }\)
Second, add the sales tax:
Total amount paid \(=38.39 \text { USD }+38.39 \text { USD }(6 \%)=38.39+38.39(0.06)=38.39+2.30=40.69 \text { USD }\)
