Can someone please check my work and assist with question 2c thank you!

"In my opinion, we ought to stop making our own drums and accept that outside supplier's offer," said Wim Niewindt, managing director of Antilles Refining, N.V., of Aruba. "At a price of 114 florins per drum, we would be paying 10 florins less than it costs us to manufacture the drums in our own plant. (The currency in Aruba is the florin, denoted by Afl.) Since we use 280,000 drums a year, we would save 2,800,000 florins on an annual basis." Antilles Refining's present cost to manufacture one drum follows (based on 280,000 drums per year): Afl 33.70 25.00 16.00 Direct material Direct labour Variable overhead Fixed overhead (Af118.60 general company overhead, Af116.20 depreciation and, Af114.50 supervision) Total cost per drum 49.30 Afl124.00 A decision about whether to make or buy the drums is especially important at this time, since the equipment being used to make the drums is completely worn out and must be replaced. The choices facing the company are as follows: Alternative 1: Purchase new equipment and continue to make the drums. The equipment would cost Af13,780,000; it would have a five-year useful life and no salvage value. The company uses straight-line depreciation. Alternative 2: Purchase the drums from an outside supplier at Afl114 per drum under a five-year contract. The new equipment would be more efficient than the equipment that Antilles Refining has been using and, according to the manufacturer, would reduce direct labour and variable overhead costs by 30%. The old equipment has no resale value. Supervision cost (Af14,060,000 per year) and direct materials cost per drum would not be affected by the new equipment. The new equipment's capacity would be 4,060,000 drums per year. The company has no other use for the space being used to produce the drums. The company's total general company overhead would be unaffected by this decision. Required: 1-a. Calculate the total costs and costs per drum under the two alternatives.
