JL.53 Bob's Bumpers has a repetitive manufacturing facility in
Kentucky that makes automobile bumpers and other auto body parts.
The facility operates 320 days per year and has annual demand of
57,000 bumpers. They can produce up to 435 bumpers each day. It
costs $50 to set up the production line to produce bumpers. The
cost of each bumper is $88 and annual holding costs are $35 per
unit. Setup labor cost is $23 per hour.
What is the optimal size of the production run for bumpers?

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 the nearest
whole number.)
Based on your answer two questions back, how many production runs
will be required each year to satisfy demand? HINT: As a general
rule, whenever calculating a value that is based on previous
calculations in Excel, always be sure to use cell references rather
than a rounded value as a calculation input. (Display your answer
to the nearest whole number.)
Suppose the customer (an auto manufacturer) wants to purchase in
lots of 260 and that Bob's Bumpers is able to reduce setup costs to
the point where 260 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 two
decimal places.)
