Write the objective function that describes the problem.An office manager needs to buy new filing cabinets. Cabinet A costs $5, takes up 5 square feet of floor space, and holds 7 cubic feet of files. Cabinet B costs $8, takes up 8 square feet, and holds 13 cubic feet. He has only $74 to spend and the office has room for no more than 74 square feet of cabinets. Let x equal the number of cabinet A's bought and y equal the number of cabinet B's bought.
A. z = 10x + 3y B. z = 3x + 10y C. z = 13x + 7y D. z = 7x + 13y
