A company rents a small building with 10,000 square feet of space for $100,000 per year. The rent is allocated to the company's three departments on the basis of the value of the space occupied by each. Department One occupies 1,500 square feet of ground-floor space, Department Two occupies 3,500 square feet of ground-floor space, and Department Three occupies 5,000 square feet of second-floor space. If rent for comparable floor space in the neighborhood averages $15.00 per sq. ft. for ground-floor space and $10.00 per sq. ft. for second-floor space, what annual rent expense should be charged to each department?
