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 3 pairs and notices that the socks do not ring up at the advertised sale price, so she has the cashier do a price check. If the sales tax is 8%, how much does Xaoting save by paying attention at the register?
a.
$3.66
b.
$4.50
c.
$4.86
d.
$5.70

Answer 1

Regular total = 3 × $5 = $15; with tax = $15 × 1.08 = $16.20.
Sale total = 3 × $3.50 = $10.50; with tax = $10.50 × 1.08 = $11.34.
Savings = $16.20 − $11.34 = $4.86.

Answer: c. $4.86
