A restaurant meal for a group of people cost $85 total. This amount included a 6% tax and an 18% tip, both based on the price of the food. Which equation could be used to find f, the cost of the food

2 answers

f + .06f + .18f = 85.00
or
1.24f = 85.00
85 - 0.06x - 0.18x = x

85 = x + 0.06x + 0.18x

85 = 1.24x

85/1.24 = x

68.55 = x
