Answer:
A). Ending Inventory = Beginning Inventory + Units Produced-Sales
Example
For March = 9375-4250 = 5125
For April = 5125+9375-8250 = 6250
B). ) Inventory cost = $12*Ending Inventory
Financing Cost = 0.01*Inventory Cost
For March = 12* 5125 = 61500 = Inventory Cost
Financing Cost = 0.01*61500 = $615
Adding for all months
Total Financing cost = $1620
