Question

Barbara is buying 4 binders, and each binder costs the same amount. She uses a coupon that gives her $3 off for the total purchase price of the binders. Barb pays a total of $11 when the value of the coupon is subtracted. Which equation shows how to find p, the original price of each binder?

Answer 1

Equation is 4 p-3=11

Explanation:

Barbara is buying 4 binders each cost same amount.

Let the cost of 1 binder is '$p'.

So, cost of 4 binders = $4 p.

Now, a coupon that gives her $3 off.

So, Barb needs to pay 4 p-3 dollars.

Barb pays a total of $11 when the value of the coupon is subtracted.

So, we can set up equation as

4 p-3=11
