Set up the linear programming problem.An office manager is buying used filing cabinets. Small file cabinets cost $5 each and large file cabinets cost $11 each, and the manager cannot spend more than $73 on file cabinets. A small cabinet takes up 7 square feet of floor space and a large cabinet takes up 10 square feet, and the office has no more than 86 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.
