do step by step help me understand in a simple way as I am having trouble, thank you

Exercise 5 Heuristic for capacity allocation 1. Serve all Priority 1 (P1) first using Regular capacity. If not enough, use Overtime; if still not enough, Outsource. 2. Serve Priority 2 (P2) with any remaining Regular, then Overtime. 3. If P2 remains, either Backlog (carry to next period) up to a cap, and Outsource the rest (use least-cost principle with backlog cap). Problem Data (3 Periods) Capacities policies (each month): e Regular capacity = 900 h e Overtime capacity = 200 h e Backlog cap at end of month = 150 h (P2 only) Costs: Regular = $50/h, Overtime = $75/h, Outsource = $85/h, Backlog penalty = $20/h Forecast loads (hours): 350 | 900 Tao : 450 | 950 | 1400 3 500 | 1100 | 1600 Tableau (fill all allocations, backlog, and cost) Month | Reg Pl | OT P1 | Out P1 | Reg P2 | OT P2 | Out P2 | Backlog End | Cost Total Cost over 3 months =
