Question

Claire purchases a new dress for the prom. The dress is priced $160, but it is on sale for 30% off. Claire’s aunt works at the store and can give her an additional 10% off. If the sales tax is 7.5%, how much does Claire pay for the dress?
a.
$93.24
b.
$103.20
c.
$108.36
d.
$120.40

Answer 1

Start with $160.
After 30% off: 160 × 0.70 = $112.
Then 10% off that: 112 × 0.90 = $100.80.
Add 7.5% tax: 100.80 × 1.075 = $108.36.

Answer: c. $108.36
