The distance between A and B is 150 miles. If the distance from A to Y is X miles, then the distance from B to Y is (150 - X) miles. Assume:

-A is the factory and B is a distribution center

-Cost at A is $200 and cost from B is $200 plus TL transportation from A to B

-TL transportation and inventory-carrying costs are $20 per unit

-Transportation costs from either A or B are $0.20 per unit per mile.

Decide when to distribute direct from factory, and from where to ship from the distribution center.
