Waterway Inc. is considering modernizing its production facility by investing in new equipment and selling the old equipment. The following information has been collected on this investment: Depreciation is $10,210 per year for the old equipment. The straight-line depreciation method would be used for the new equipment over an eight-year period with salvage value of $5,000. (a) Determine the cash payback period. (Ignore income taxes.) (Round answer to 3 decimal places, e.g. 15.275.) Determine the cash payback period. (Ignore income taxes.) (Round answer to 3 decimal places, e.g. 15.275.) (b) Calculate the annual rate of return. (Round answer to 2 decimal places, e.g. 15.25\%.) Calculate the net present value assuming a 15% rate of return. (Ignore income taxes.) (If the net present value is negative, use either a negative sign preceding the number eg. - 45 or parentheses eg. (45). For calculation purposes, use 5 decimal places as displayed in the factor table provided, eg. 1.25124 and final answer to 0 decimal places, eg. 5,275.) Click here to view the factor table.
