Answer 1

You have to add
So the coupon subtracts 17.95 from X price and you pay $71.80 for the headphones
17.95 + 71.80 = $89.75 (Original Price)

Answer 2

`P-17.95=71.80`

Original cost: $89.75.

Explanation:

Let P represent the original price of the headphones.

We have been given that a coupon subtracts $17.95 from the price P of a pair of headphones.

The cost of headphones after using the coupon would be
`P-17.95`.

We are also told that you pay $71.80 for the headphones after using the coupon. We can represent this information in an equation as:

`P-17.95=71.80`

Let us solve for P.

`P-17.95+17.95=71.80+17.95`

`P=89.75`

Therefore, the original cost of headphones is $89.75.
