Respuesta :

Answer:

Equation is 4 p-3=11

Step-by-step 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
