The original amount of money on the gift card was $45 and after buying 8 cups of coffee, the card had a $25 remaining balance. Write an equation for A, in terms of x, representing the amount money remaining on the card after buying 2 cups of coffee.

Answer 1

Answer:

Results are below.

Step-by-step 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

Answer 2

Answer: 45-2.5x
