Jones Excavation Company is planning an investment of $177,900for a bulldozer. The bulldozer is expected to operate for 2,000hours per year for five years. Customers will be charged $120 perhour for bulldozer work. The bulldozer operator costs $38 per hourin wages and benefits. The bulldozer is expected to require annualmaintenance costing $20,000. The bulldozer uses fuel that isexpected to cost $50 per hour of bulldozer operation.

c. Should Jones invest in the bulldozer, basedon this analysis?
, because the bulldozer cost is   the present valueof the cash flows at the minimum desired rate of return of 6%.

d. Determine the number of operating hours suchthat the present value of cash flows equals the amount to beinvested. Round interim calculations and final answer to thenearest whole number.
