Question

Tim uses a food delivery service to order dinner for himself and a friend. He paid $37.05 for dinner, which included the cost of the food and a delivery fee of 14% of the cost of the food. What was the cost of their dinner before the delivery fee?

Please explain!

Answer 1

$31.86

Explanation:

You can use a proportion here.

37.05 = 100%

x = 86% (100%-14% which is a delivery fee)

x = (37.05*86)/100

x = 3186.3/100

x = 31.86

The cost of their dinner before the delivery fee was $31.86.
