Question

While out shopping for new clothes, Xaoting sees a sign for cozy socks advertised on sale for $3.50 per pair. The regular price of the socks is $5 per pair. Xaoting buys three pairs and notices that the socks do not ring up at the advertised sale price, so they have the cashier do a price check. If the sales tax is 8%, how much does Xaoting save by paying attention at the register?

$3.66
$4.50
$4.86
$5.70

Answer 1

Regular total: 3 × \$5 = \$15; sale total: 3 × \$3.50 = \$10.50.
Include 8% tax: regular = \$15(1.08) = \$16.20, sale = \$10.50(1.08) = \$11.34.
Savings = \$16.20 − \$11.34 = \$4.86.

Answer: \$4.86
