Question

1) Paula buys 5 sandwiches. Each sandwich is the same price. She has a coupon for $2 off the entire purchase. She pays a total of $50.

• Which equation can be used to find the price, x, of one sandwich?

5(x + 2) = 50
5x + 2 = 50
5(x − 2) = 50
5x – 2 = 50

Answer 1

5x - 2 = 50

I READY!!!

holpe it help

Answer 2

5x - 2 = 50

Explanation:

The coupon takes $2 OFF the entire purchase, so we eliminate answers A and B. If we take away $2 off the price of each sandwich, then that would be a $10 coupon, so we eliminate C. The only answer left is D, so D is the answer.
