Question 6
6. There are 25 plastic storage containers on the store shelf. The width of each plastic storage container is 12
inches or 18 inches. The width of all 18 inch containers combined is 306 inches.
Which system of equations can be used to find the number of 12-inch plastic containers, x, and the number of
18-inch plastic containers, y, that are on the shelf?
A.
18x = 306
12x + 18y = 25
B. 18x = 306
18x +12y = 25
10 pts
C. x - y = 25
18y = 306
D. 18y = 306
y = 25-x
