Answer:
$75
Step-by-step 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:
The dinner was $75
Step-by-step 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
