A company is considering replacing an old piece of machinery, which cost $601,800 and has $352,600 of accumulated depreciation to date, with a new machine that has a purchase price of $485,700. The old machine could be sold for $64,400. The annual variable production costs associated with the old machine are estimated to be $155,400 per year for eight years. The annual variable production costs for the new machine are estimated to be $100,400 per year for eight years.

a. Prepare a differential analysis dated April 29 to determine whether to continue with (Alternative 1) or replace (Alternative 2) the old machine. If an amount is zero, enter "0". For those boxes in which you must enter subtracted or negative numbers use a minus sign.
