Question

the silver town people went to a fancy restaurant after the big event. Grammy gave the server a 15$ tip. If the tip was 20% of the cost of dinner, how much was dinner. what is the answer

Answer 1

$15

Explanation:

Let d represent the cost of the dinner before tip. Then $15 = 0.20d, since 0.20 is the decimal fraction corresponding to 20%.

Solving for d, the cost of the dinner, we divide both sides of the equation $15 = 0.20d by .20, obtaining:

$15

d = ------------ = $75

0.20

The cost of the dinner before tip was $75.
