Question

Can anyone help? Estimate the amount of the tip by rounding the bill to the nearest dollar before calculating.

20% tip on a bill of $64.15

Answer 1

$12.80

Explanation:

You are asked to estimate the tip by rounding the bill amount. The tip is the product of the (rounded) bill amount and the tip rate.

rounded bill = $64.00

tip rate = 20% = 0.20

estimated tip = 0.20 × $64.00 = $12.80
