7. Campaign Printing has two service departments. Si and 52, and two producun depan P2. The data for May were as follows: and two production departments, Pland Activity Si S2 Costs $90,000 $60,000 Fixed Costs $360,000 $520,000 Services provided to S1 S2PLP2 10% 40% 50% 20% 55% 25% Pl P2 Required: Allocate service departments costs (S1 & S2) to the production departments (PI & P2) Wing reciproca method a. Set up linear equations to solve for the total costs incurred in S1 and 52. (Note: if you use repeated iteration, you won't get any points!!!) Determine total costs for each department by first solving the equations from parts then performing the necessary allocation. (note: round to the nearest integer). b
