Question

James works as a waiter. He served meals with bills of $23.59, $40.65, $30.50, and $15.68. If his total for tips was $17.67, what percent tip did he receive for serving these meals? Round your answer to the nearest percent?

Answer 1

Cross multiply and divide. 17.67x100=1,767 divided by 23.59 = 74.90 then do 23.59x74.90 divided by 17.67 = 99.99 so 75 percent when rounded

Answer 2

Add the total bills:

23.59 + 40.65 + 30.50 + 15.68 = 110.42

Divide his tips by the total bills to get the rate of the tips

17.67 ÷ 110.42 = 0.16
0.16 x 100% = 16%

His tips were 16% of the bills.

To check:
23.59 x 16% = 3.7744
40.65 x 16% = 6.504
30.50 x 16% = 4.88
15.68 x 16% = 2.5088
total tips 17.6672 rounded off to 17.67
