Given the following information set up the problem in atransportation table and solve for the minimum-cost plan:
| PERIOD |
| 1 | 2 | 3 |
| Demand | | 550 | 700 | 750 |
| Capacity | | | | |
| Regular | | 500 | 500 | 440 |
| Overtime | | 50 | 50 | 50 |
| Subcontract | | 120 | 120 | 100 |
| Beginning inventory | | 100 | | |
| Costs | | | | |
| Regular time | $ | 60 per unit |
| Overtime | $ | 80 per unit |
| Subcontract | $ | 90 per unit |
| Inventory carrying cost | $ | 1 per unit permonth |
| Back-order cost | $ | 3 per unit permonth |
|
Suppose that an inventory carrying cost is increased $2 per unitper period. What will the additional cost of the optimal plan be?(Omit the "$" sign in your response.)
Additional cost         $
I've asked this question a couple of times and it has beenincorrect. So.. the answer is not 440 haha.. good luck! Thanks foryour help!
