Exercise 23-06 al-a2 Vaughn, 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 smartphone. The cost structure to manufacture 21,200 Tri-Robos is as follows. Direct materials ($51 per robot) Direct labor ($42 per robot) Variable overhead ($6 per robot) Allocated fixed overhead ($28 per robot) Total Cost $1,081,200 890,400 127,200 593,600 $2,692,400 Vaughn is approached by Tienh Inc., which offers to make Tri-Robo for $117 per unit or $2,480,400. Following are independent assumptions. Assume that $405,000 of the fixed overhead cost can be avoided. (Enter negative amounts using either a negative sign preceding the number e.g. -45 or parentheses e.g. (45).) Net Income Increase (Decrease) Make Buy Direct materials Direct labor Assume that $405,000 of the fixed overhead cost can be avoided.

Net Income Increase (Decrease) Make Direct materials Direct labor Variable overhead Fixed overhead Purchase price Total annual cost Using incremental analysis, determine whether Vaughn should accept this offer. The offer Assume that none of the fixed overhead can be avoided. However, if the robots are purchased from Tienh Inc., Vaughn can use the released productive resources to generate additional income of $375,000.
