The annual variable production costs for the new machine are estimated to be $98,600 per year for eight years. a.1 Prepare a differential analysis dated September 13, to determine whether to continue with (Alternative 1) or replace (Alternative 2) the old machine. If an amount is zero, enter "o". For those boxes in which you must enter subtracted or negative numbers use a minus sign. Differential Analysis Continue with Old Machine (Alt. 1) or Replace Old Machine (Alt. 2) September 13 Continue with Old Machine (Alternative 1) Replace Old Machine (Alternative 2) Differential Effect on Income (Alternative 2) Revenues: Proceeds from sale of old machine Costs: Purchase price Variable productions costs (8 years) Income (Loss) a.2 Determine whether to continue with (Alternative 1) or replace (Alternative 2) the old machine
