Question

The silver town people went to a fancy restaruant after the big event.Grammy gave the server a $15 tip.If the tip was 20 percent of the cost of dinner,how much was dinner.

Answer 1

$75.

Explanation:

We have been given that Grammy gave the server a $15 tip. The tip was 20% of the cost of dinner.

Let x be the cost of Grammy's dinner. We need to find x such that 20% of x equals to 15. We can represent this information as:

`(20)/(100)x=15`

`0.20 x=15`

`x=(15)/(0.20)`

`x=75`

Therefore, the cost of Grammy's dinner was $75.
