   Briggs Excavation Company is planning an investment of $153,700 for a bulldozer. The bulldozer is expected to operate for 1,000 hours per year for seven years. Customers will be charged $130 per hour for bulldozer work. The bulldozer operator costs $34 per hour in wages and benefits. The bulldozer is expected to require annual maintenance costing $10,000. The bulldozer uses fuel that is expected to cost $45 per hour of bulldozer operation.

   b. Determine the net present value of the investment, assuming that the desired rate of return is 20%. Use the The sum of the present values of a series of equal cash flows to be received at fixed intervals.present value of an annuity of $1 table above. Round to the nearest dollar. If required, use the minus sign to indicate a negative net present value.

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

   • Yes
   • No
   , because the bulldozer cost is
   • less than
   • more 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.
