Dinner only: $75
Dinner and Tip: $90
Step-by-step explanation:
If the tip was $15, and the tip was 20% of the price of dinner, then dinner was $75.
You can find this out by doing 15/20%, which should give you 75.
If the question requires you to add up the price of dinner and the tip, then the total price would be $90
