Briggs Excavation Company is planning an investment of $667,000 for a bulldozer. The bulldozer is expected to operate for 3,000 hours per year for 10 years. Customers will be charged $130 per hour for bulldozer work. The bulldozer operator costs $30 per hour in wages and benefits. The bulldozer is expected to require annual maintenance costing $30,000. The bulldozer uses fuel that is expected to cost $39 per hour of bulldozer operation.

c. Should Briggs Excavation invest in the bulldozer, based on this analysis?

YesNo

, because the bulldozer cost is

less thanmore than

the present value of the cash flows at the minimum desired rate of return of 20%.

d. Determine the number of operating hours such that the present value of cash flows equals the amount to be invested. Round interim calculations and final answer to the nearest whole number. fill in the blank 96d24606a01bf99_6 hours
