Problem 14-3

Refer to Figure 14-10. Billings Office Services is considering the purchase of a new computer system to replace the one in operation. Data on the new computer system are:

If the existing computer system is kept and used, it would require the purchase of additional hardware a year from now costing $2,000. After using the system for five years, the salvage value would be $300. Additional information on the existing system is:

The company uses the straight-line method of depreciation.

Required:

Compute the net present value of the new computer system. $

Should the new system be purchased?
