Answer 2

Results are below.

Explanation:

Giving the following information:

The original amount of money on the gift card was $45. After buying 8 cups of coffee, the remaining balance was $25.

First, we need to calculate the unitary value of each cup of coffee:

Unitary cost= 20/8= $2.5

Now, we can structure the remaining balance formula (A):

A= 45 - 2.5x

x= cup of coffee

After 2 cups:

A= 45 - 2.5*2

A= 40
