B8. The
following appeared in a presentation by the chief production manager of a
machine parts manufacturing company at a management meeting:

“Our
factory in Cookville is our most advanced and efficient. It is capable of producing
ten drill bits for each dollar of production costs, whereas none of our other
factories can produce more than seven drill bits per dollar of production
costs. Therefore, we can reduce our overall drill bit production costs by
devoting the Cookville factory entirely to drill bit production. Since reducing
the production costs of individual machine parts is the only way to achieve our
larger goal of reducing our overall production costs, dedicating the Cookville
factory entirely to drill bit production and shifting all other machine part
production to our other factories will help us to attain that larger goal.”
