E7-6 Jobs, Inc. has recently started the manufacture of Tri-Robo, a three-wheeled robot that can scan a home for fires and gas leaks and then transmit this information to a mobile phone. The cost structure to manufacture 20,000 Tri-Robos is as follows. Direct materials ($50 per robot) Direct labor ($40 per robot) Cost $1,000,000 800,000 120,000 Allocated fixed overhead ($30 per robot) 600,000 Total $2,520,000 Variable overhead ($6 per robot) Jobs is approached by Tienh Inc., which offers to make Tri-Robo for $115 per unit or $2,300,000. Instructions (a) Using incremental analysis, determine whether Jobs should accept this offer under each of the following independent assumptions. (1) Assume that $405,000 of the fixed overhead cost can be reduced (avoided). (2) Assume that none of the fixed overhead can be reduced (avoided). However, if the robots are purchased from Tienh Inc., Jobs can use the released productive resources to generate additional income of $405,000. (b) Describe the qualitative factors that might affect the decision to purchase the robots from an outside supplier.
