Question
![North Platt Machinery Company manufactures a shaft that must fit inside a sleeve. The firm has just received an order of 58,000 units
from Southernstar Exploration Company for $68 per unit. North Platt can manufacture the shaft at $38 per unit. Southernstar desires
the diameter of the shaft to be 1.283 cm. The diameter of the shaft must not be less than 1.258 cm in order to fit properly inside the
sleeve. To be able to insert the shaft into a sleeve without the use of force, the diameter cannot be larger than 1.308 cm. A defective
shaft is discarded and a replacement has to be shipped via express freight to locations around the world. North Platt estimates that the
average cost of handling and shipping a replacement shaft will be approximately $58. Shown below are the diameters from a sample
of 80 shafts manufactured during a trial run:
