Question

A group of friends receives a dinner bill for $87.50$87.50. The sales tax rate is 5%5%. They want to leave a 15%15% tip on the total bill after tax. How much money will they pay for their dinner with tax and tip?

Answer 1

I got $105.66

Explanation:

I multiplied the subtotal by .05(to represent sales tax %) then added the solution to $87.50. then I multiplied .15(tip) to $87.50. Added that to the previous solution and got $105.66. Read below for clarification.

87.50(.05) = 4.375(or 4.38)

87.50 + 4.375 = 91.875

87.50(.15) = 13.125

91.875 + 13.125 = $105.66

Answer 2

105.66

Explanation:

87.5 times 1.05= 91.875

then you do 91.875 times 1.15 = 105.656
