Question

Allam just finished a great meal at a restaurant in Wisconsin. The sales tax in Wisconsin is 5%, and it is customary to leave a tip of 15% for the server. The tip amount is calculated on the price of the meal before the tax is applied. (Sales tax is not calculated on tips.)

If Allam ordered a $15 meal, how much money will he have to pay with tax and tip?

Answer 1

$18

Explanation:

15 : 100 = x : 15

x = 15 · 15 / 100

x = 225 / 100

x = $ 2.25 (tips)

5 : 100 = x : 15

x = 15 · 5 / 100

x = 75 / 100

x = $ 0.75 (tax)

15 + 0.75 + 2.25 = $18
