A local bakery sells cookies for 5.50 per pound and brownies for 7.50 per pound. The following equations represent the sales for a random
day.
5.50x + 7.50y = 63
+y=10
Which of the following is true of the purchase?

A. The store sold 10 pounds of brownies and made a total of $63
B. The store sold 10 pounds of cookies and made a total of $36
C. The variable, x, represents the pounds of cookies sold in the $63 purchase
D. The variable, y, represents the pounds of cookies sold in the $63 purchase

I may be wrong but i think the answer is D

Step-by-step explanation:

We know that y=10, so if we were to multiply 10 by 7.50, it would be 75, not 63, so A and B wouldn't be correct. and we don't know the value of x, so I think D is the best answer.
