Question

Bao goes out to lunch. The bill, before tax and tip, was $15.80. A sales tax of 4.5% was

added on. Bao tipped 15% on the amount after the sales tax was added. How much tip
did she leave? Round to the nearest cent.

Answer 1

$18.59

Explanation:

Tax:

15.80 x .045 = .711

Cost after tax:

15.80 +.711 = 16.511

Tip:

16.511 x .15 = 2.47665

Total cost

16.511 + 2.47665 = 18.58665 Rounded to the nearest penny is $18.59
