I like to see the math so I can see what I am doing wrong. Thank you in advance!

Required information The Ferre Publishing Company has three service departments and two operating departments. Selected data from a recent period on the five departments follow: Administration is allocated based on number of employees; Janitorial based on space occupied; and Maintenance based on hours c press time. Required: Assuming that the company uses the direct method to allocate service department costs, how much cost would be assigned to each perating department? (Please enter allocations from a department as negative and allocations to a department as positive. The ine should add across to zero. Do not round intermediate calculations.)
