Question

A store has 7 bags of sugar in an aisle. Each small bag weighs 4 pounds. each large bag weighs 10 pounds. There are 52 pounds of sugar in the aisle. Write a system of equations for the situation. Be sure to identify what your variables represent.

Answer 1

Answer: 4 small bags, 3 large bags (equations below in explanation)

Explanation:

x=number of small bags

y=number of large bags

x+y=7

4x+10y=52

Subtract them after multiplying the first equation by 4.

4x+4y=28

4x+10y=52

-6x=-24

x=4

x+y=7

4+y=7

y=3
