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 square foot for ground-floor space and $10.00 per square foot for second-floor space, what annual rent expense should be charged to each department?
