Briscoe Co. produced a pilot run of a recently developed piston used in one of its products. Briscoe expected to produce and sell 39 units annually. The pilot run required an average of 27.5 direct labor hours. Briscoe experienced an eighty percent learning curve on the direct labor hours needed to produce new pistons. Past experience indicated that learning tends to cease by the time 16 pistons are produced. Briscoe's manufacturing costs for pistons are presented below. a. The cumulative average direct labor hours per unit for the first 16 pistons (including the pilot run) produced is: b Find the marginal direct labor hours per unit for Briscoe's production beyond 16 pistons. c Calculate Briscoe's manufacturing costs for the additional 38 pistons beyond the pilot run. de Briscoe received a quote of $450 per unit from Stone Machine Co. for the additional 38 units needed. Briscee frequently subcontracts this type of work and has always been satisficd with the quality of the units produced by Stonc. Should Briscoe produce the pistons or subcontract with Stone?
