Problem
A firm plans to begin production of a new small appliance. The manager must decide whether to purchase the motors for the appliance from a vendor at $9 each or to produce them in-house.
Either of two processes could be used for in-house production; Process A would have an annual fixed cost of $170,000 and a variable cost of $5 per unit, and Process B would have an annual fixed cost of $190,000 and a variable cost of $4 per unit.
Determine the range of annual volume for which each of the alternatives would be best.
(Round your first answer to the nearest whole number. Include the indifference value itself in this answer. Enter your last answer as a whole number).
For annual volumes of or less, is best. For annual volumes at or above that amount, it is best to produce in house at a cost of $ per unit.
