9. Assume that Darrow Co. is considering disposing of equipment that cost $50,000 and has $40,000 of accumulated depreciation to date. Darrow Co. can sell the equipment through a broker for $25,000 less 5% commission. Alternatively, Minton Co. has offered to lease the equipment for five years for a total of $48,750. Darrow will incur repair, insurance, and property tax expenses estimated at $10,000. At lease-end, the equipment is expected to have no residual value. The net differential income from the lease alternative is: a $15,000 b. $5,000 c. $25,000 d. $12,500 10. Frank Co. is currently operating at 80% of capacity and is currently purchasing a part used in its manufacturing operations for $5 a unit. The unit cost for Frank Co. to make the part is $6, which includes $.40 of fixed costs. If 4,000 units of the part are normally purchased each year but could be manufactured using unused capacity, what would be the amount of differential cost increase or decrease for making the part rather than purchasing it? a $12,000 cost decrease b. $20,000 cost increase c. $20,000 cost decrease d. $2,400 cost increase 17. Carnival Corp. is considering selling its old popcorn machine and replacing it with a newer one. The old machine originally cost $5,000 and has been fully depreciated. Annual costs are $4,000. A high school is willing to buy it for $2,000. New equipment would cost $18,000 and annual operating costs would be $1,500. Both machines have an estimated useful life of 5 years. a. Stay with the old equipment $3,500 less in net costs b. Purchase the new equipment $3,500 cost savings c. Purchase the new equipment - deduction in costs $14,500 d Stay with the old equipment - cost savings of $2,000 34. The expected average rate of return for a proposed investment of $4,800,000 in a fixed asset, using straight line depreciation, with a useful life of 20 years, no residual value, and an expected total net income of $12,000,000 is: a 25% b. 18% c. 40% d. 12.5%
