Please solve Problem 2 correctly

Problem 2: Suppose that production planning is to be done for the next 5 months, where the respective demands are r1=2,r2=4,r3=2,r4=2, and r5=3. The setup cost is $4,000, the unit production cost is $1,000, and the unit holding cost is $300. Use the deterministic periodic-review model to determine the optimal production schedule that satisfies the monthly requirements. Write down the optimal production schedule. Note: optimum production schedule is independent of the unit cost, however, add this cost to your calculation to find the total cost of the production
