Answer:

A

Why:

$65.00-$15.00=$50.00

She visited 5 stores, and she bought 7 items.

So therefore it would be A.

Sorry that my answer was short.

Answer:

A.) 7x x 5=$50.00

Step-by-step explanation:

You can eliminate B and C as they don't include the 5 different stores.

D is incorrect because it doesn't include the 7 items.

Therefore, A is correct because 7x is the 7 items multiplied by the average cost per item and you multiply by 5 because she does that at each of the 5 stores. It = to 50 because she started with $65 but ends up with $15 so you subtract $65 with $15 to get $50 as that's how much she spent.
