17.95 + 71.80 =  $89.75 (Original Price)

Answer 2

Answer:

$P-17.95=71.80$

Original cost: $89.75.

Step-by-step 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.
