Solve the problem.

An office manager is buying used filing cabinets. Small file cabinets cost $7 each and large file cabinets cost $12 each, and the manager cannot spend more than $104 on file cabinets. A small cabinet takes up 7 square feet of floor space and a large cabinet takes up 9 square feet, and the office has no more than 92 square feet of floor space available for file cabinets. The manager must buy at least 7 file cabinets in order to get free delivery. Let x = the number of small file cabinets bought and y = the number of large file cabinets bought. Write a system of inequalities that describes these constraints.

▸ 7x + 12y ≤ 104
9x + 7y ≤ 92
x ≥ 7

▸ 7x + 12y ≤ 104
7x + 9y ≤ 92
x + y ≤ 7

▸ 7x + 12y ≤ 104
7x + 9y ≤ 92
y ≥ 7

▸ 7x + 12y ≤ 104
7x + 9y ≤ 92
x + y ≥ 7
