The price of a family dinner was $48.00. A sales tax added 5% to the final bill. The family then left a $10.08 tip. If the family included the sales tax when calculating the tip, what percent tip did the family leave?
First calculate the sales tax: (48.00)(.05) =2.40
48.00 + 2.40 = 50.40
to calculate how much tip they left, substitute x for the percent.
(50.40)(x) = 10.08
divide both sides by 50.4 to isolate x
x = 0.2
The family left a 20% tip.
Hope this helps!
