Net Present Value Method-Annuity Briggs Excavation Company is planning an investment of $253,800 for a bulldozer. The bulldozer is expected to operate for 1,000 hours per year for six years. Customers will be charged $130 per hour for bulldozer work. The bulldozer operator costs $25 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 $33 per hour of bulldozer operation.

Determine the equal annual net cash flows from operating the bulldozer. Use a minus sign to indicate cash outflows. 1,000 130 870 X Briggs Excavation Equal Annual Net Cash Flow Cash inflows: Hours of operation Revenue per hour Revenue per year Cash outflows: Hours of operation Fuel cost per hour 33 Labor cost per hour 25 Total fuel and labor costs per hour Fuel and labor costs per year 1,000 58 508,080 x 30 x Maintenance costs per year Annual net cash flow 62,000 b. Determine the net present value of the investment, assuming that the desired rate of return is 10%. Use the 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. Present value of annual net cash flows $ 270,010 Amount to be invested 253,800 Net present value 16,210 C. Should Briggs Excavation invest in the bulldozer, based on this analysis? Yes, because the bulldozer cost is less than the present value of the cash flows at the minimum desired rate of return of 10%. 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. 980 X hours
