Waterways has discovered that a small fitting it now manufactures at a cost of $1.00 per unit could be bought elsewhere for $0.83 per unit. Waterways has fixed costs of $0.20 per unit that cannot be eliminated by buying this unit. Waterways needs 452,000 of these units each year. If Waterways decides to buy rather than produce the small fitting, it can devote the machinery and labor to making a timing unit it now buys from another company. Waterways uses approximately 400 of these units each year. The cost of the unit is $12.56. To aid in the production of this unit, Waterways would need to purchase a new machine at a cost of $2,321, and the cost of producing the units would be $9.70 a unit.

Without considering the possibility of making the timing unit, evaluate whether Waterways should buy or continue to make the small fitting.

Would it be wise for Waterways to buy the fitting and manufacture the timing unit?
