Answer 1

Answer:

$75.  

Step-by-step explanation:

We have been given that Grammy gave the server a $15 tip. The tip was 20% of the cost of dinner.

Let x be the cost of Grammy's dinner. We need to find x such that 20% of x equals to 15. We can represent this information as:

$\frac{20}{100}x=15$

$0.20 x=15$

$x=\frac{15}{0.20}$  

$x=75$

Therefore, the cost of Grammy's dinner was $75.
