If Companion Computer Company manufactures the carrying cases, fixed factory overhead costs will not increase and variable factory overhead costs associated with the cases are expected to be 13% of the direct labur cusls. a. Prepare a differential analysis dated February 24 to determine whether the company should make (Alternative 1) or buy (Alternative 2) the carrying case. If required, round your answers to two decimal places. If an amount is zero, enter "0". For those hoxes in which you must enter subtracted or negative numbers use a minus sign. Differential Analysis Make Carrying Case (Alt. 1) or Buy Carrying Case (Alt. 2) February 24 Make Carrying Buy Carrying Differential Effect Case (Alternative 1) Case (Alternative 2) on Income (Alternative 2) 0 Sales Price () 0 Costs: Purchase price si $ 62 $ 62 X Direct materials per unit 30 0 30 Direct labor per unit 20 0 20 Variable factory overhead per unit 2.6 X 2.6 Fixed factory overhead per unit 5.
