Question

The silver tell people went to a fancy restaurant after the big TV Grammy gave the survey $15 tip if the tip is 20% of the cost of dinner how much was dinner

Answer 1

$75

Explanation:

$15 is only 20%

we need 100% to find the cost of the dinner

20% times 5 equals 100%

so 15x5 = 75

cost of dinner = $75

Answer 2

The dinner was $75

Explanation:

First we need to determine the tip

We know the tip was $15 and the tip rate was 20 %

tip = cost of the dinner * tip rate

Substitute the known values in

15 = cost of the dinner *.2

Divide each side by .2

15/.2 = cost of the dinner *.2/.2

75= cost of the dinner
