What would be the net present value of a microwave oven that costs $159 and will save you $68 a year in time and food away from home? Assume an average return on your savings of 4 percent for five years. (Hint: Calculate the present value of the annual savings, then subtract the cost of the microwave.) Use Exhibit 1-D. (Round PVA factor to 3 decimal places and final answer to 2 decimal places.)
