Question

Arthur is treating his friends to a meal at Chez Rich. The meals added up to $152.30. If he tips the waiter 15%, what is the amount of the tip.

a. $20.80
b. $15.24
c. $22.85
d. $13.37

Answer 1

This is a simple multiplication problem and it goes like this:

153.30 * (15/100)

153.30 * 0.15 (changed from a percent to a decimal but have the same value)

22.845 --> 22.85

The tipi is $22.85

Answer 2

152.30(0.15) = 22.845
Round 22.845 to $22.85
So the answer is C. (:
