Net present value-unequal IIves Dakota Mining Company has two competing proposals: a diamond core drill or a hydraulic excavator. Both pieces of equipment have an initial investment $682,672. The cash flows estimated for the two proposals are as follows: The estimated residual value of the diamond core drill at the end of Year 4 is $290,000. The estimated residual value of the diamond core drill at the end of Year 4 is $290,000. Determine which equipment should be favored, comparing the net present values of the two proposals and assuming a minimum rate of return of 15%. the prent table appearing above
