Ellison Inc., a manufacturer of steel school lockers, plans to purchase a new punch press for use in its manufacturing process. After contacting the appropriate vendors, the purchasing department received differing terms and options from each vendor. The Engineering Department has determined that each vendor's punch press is substantially identical and each has a useful life of 20 years. In addition, Engineering has estimated that required year-end maintenance costs will be $1,010 per year for the first 5 years, $1,980 per year for the next 10 years, and $2,780 per year for the last 5 years. Following is each vendor's sale package.
Vendor A: $57,890 cash at time of delivery and 10 year-end payments of $18,370 each. Vendor A offers all its customers the right to purchase at the time of sale a separate 20-year maintenance service contract, under which Vendor A will perform all year-end maintenance at a one-time initial cost of $11,040.
Vendor B: Forty semiannual payments of $9,780 each, with the first installment due upon delivery. Vendor B will perform all year-end maintenance for the next 20 years at no extra charge.
Vendor C: Full cash price of $143,820 will be due upon delivery.
Assuming that both Vendors A and B will be able to perform the required year-end maintenance, that Ellison's cost of funds is 10%, and the machine will be purchased on January 1, compute the following: (Use the tables below.)
1. The present value of the cash flows for vendor A.
2. The present value of the cash flows for vendor B.
3. The present value of the cash flows for vendor C.
4. From which vendor should the press be purchased?
