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 smartphone. The cost structure to manufacture 21,000 Tri-Robos is as follows. Jobs is approached by Tienh Inc. which offers to make Tri-Robo for $113 per unit or $2,373,000. 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 eg. -45 or parentheses eg. (45).) Assume that none of the fixed overhead can be avoided. However, if the robots are purchased from Tienh Inc., Jobs can use the released productive resources to generate additional income of $375,000. (Enter negative amounts using either a negative sign preceding the number eg. -45 or parentheses eg. (45).)
