Ivanhoe, 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 20,400 Tri-Robos is as follows. Ivanhoe is approached by Tienh Inc., which offers to make Tri-Robo for $116 per unit or $2,366,400. Following are independent assumptions. Assume that $405,000 of the fixed overhead cost can be avoided. (Enter negative amounts using elther a negative sign preceding the number eg. 45 or parentheses eg. (45).) Using incremental analysis, determine whether Ivanhoe should accept this offer. Assume that none of the fixed overhead can be avoided. However, if the robots are purchased from Tienh Inc., Ivanhoe 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).)
