Question

Shinya went to the salon. The cost if her haircut was $16.00. He tipped the barber 15%. What was the total cost

?

Answer 1

$18.40 because 15% of 16.00 is 2.40 so 16.00 + 2.40 = 18.40.

Answer 2

total cost=costofhaircut+tip
tip=costofhaircut times percent tip
percent tip=15%

percent means parts out of 100
15%=15/100=0.15

cost of haircut=16
tip=16 times 0.15=2.4

total cost=16+2.4=18.4

total cost=$18.40
