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?

Respuesta :

.2x=15 (.2 for 20%, x is the total bill. So 20% of the total bill. 15 is how much 20% is)
x=75
so $75
The dinner cost is 75 dollars
