The cost of each bumper is $95 and annual holding costs are $25 per unit. Setup labor cost is $23 per hour.

a. Based on the above information, what is the optimal size of the production run for bumpers? (Display your answer to two decimal places.)

b. Based on your answer to the previous question, and assuming the manufacturer holds no safety stock, what would be the average inventory for these bumpers? (Display your answer to two decimal places.)

c. Based on your answer two questions back, how many production runs would be required each year to satisfy demand? (Display your answer to two decimal places.)

d. Suppose the customer (an auto manufacturer) wants to purchase these bumpers in lots of 200 and that Bob's Bumpers is able to reduce setup costs to the point where 200 is now the optimal production run quantity. How much will they save in annual holding costs with this new lower production quantity? (Display your answer to twodecimal places.)
