1. ABC Company is interested in buying a piece of equipment for $150,000. The average useful life of the equipment is anticipated to be five years, with projected annual cash flow of $22,000. Calculate the net present value of the equipment at 8%. Assume no salvage value.
2. The department you manage would like to buy a piece of equipment for $20,000 with projected cash flows of $4,500 per year over the eight-year useful life. Calculate the net present value at 10%. Assume no salvage value.

I understand on #1 the answer to the first part is $20,370.37, my question is how do you get to this answer?
