I just need help understanding how we got the overtime production in period 3, 4, and 5? It would be helpful if I got an exact calculation on how we arrived to the numbers in the chart for those periods (1000, 2,000, and 2,000)?

Also why is Ending for period 4 500? Where did that exactly come from (calculation?)

Aggregate Planning Chase Use the information below to work all the problems in this section. Work the problem very carefully and pay attention to the details. Values build on values so once you make a mistake, it is likely that all the following values will be incorrect. Demand for the next six periods: 2,000; 2,000; 3,500; 4,000; 5,000; 2,100 Maximum regular time production: 2,500 Maximum overtime production: 2,000 They use the chase strategy. If there is not enough production capacity to meet demand, where possible, they will produce earlier to build up inventory to meet that demand. The following costs are per unit: Regular time: $4.00 Overtime: $7.50 Inventory per period: $2.85 Backorders: $20.00 Develop the aggregate plan.
