Problem $5-8($Static$)$

A manager is trying to decide whether to purchase a certain part or to have it produced internally. Internal production could use either of two processes. One would entail a variable cost of $$17$ per unit and an annual fixed cost of $$200,000$; the other would entail a variable cost of $$14$ per unit and an annual fixed cost of $$240,000.$ Three vendors are willing to provide the part. Vendor A has a price of $$20$ per unit for any volume up to $30,000$ units. Vendor $B$ has a price of $$22$ per unit for demand of $1,000$ units or less, and $$18$ per unit for larger quantities. Vendor $C$ offers a price of $$21$ per unit for the first $1,000$ units, and $$19$ per unit for additional units.

a$.$ If the manager anticipates an annual volume of $10,000$ units, which alternative would be best from a cost standpoint? For $20,000$ units, which alternative would be best?
