NEED HELP solving the Production plan and the Inventory Plan. Please provide equation. I don't know if I did it right. Mostly this is kinda a guessing number. It doesn't matter what you put down as long as it doesn't go past the max and min. Only focus on the production and inventory plan.

Inventory Targets Min 20 Max 180 Production Plan Min 40 Max 140

Increment production of 10 units and change less than or equal to 20 in consecutive periods.
