A manufacturer purchases 6000 cases of a certain component for $100 per case from two suppliers: Supplier A and Supplier B.

Supplier A is currently responsible for 1/2 of the total demand. The two suppliers currently pay $2 per case for transportation and achieve the same average delivery time of 10 days. However, for each day that a supplier can reduce in the average delivery time, the manufacturer is willing to shift 5% of its total purchase to the supplier offering the premium service. A supplier earns a margin of 25% of the selling price on each case before transportation cost kicks in.

- a) How much profit does Supplier A make currently?
**Please provide at least one step of calculation and the correct answer for full credit. (4 points)**

- b) Suppose Supplier A is willing to reduce its average delivery time by 3 days and the transportation rate increases by $0.5 per case
**for each day**in the average delivery time. How much profit can Supplier A make by offering the premium transportation service? Assume that Supplier B take no action.**reduced****Please provide the new sales number, at least one step of calculation, and the correct answer for full credit. (6 points)**
