Determine the equal annual net cash flows from operating the bulldozer. Use a minus sign to indicate cash outflows. Net Fresent Value Method-Anhuity Briggs Excevation Company is planning an investment of \\( \\$ 138,200 \\) for a buldozer. The bulldorer is expected to operate for 2,000 hours per year for five years. Customers will be charged \\( \\$ 115 \\) per hour for bulidozer work: The bulldozer operator costs \\( \\$ 36 \\) per hour in wages and benefis. The bulldozer is expected to require annual maintenance costing \\( \\$ 20,000 \\). The buldozer uses fuel that is expected to cost \\( \\$ 47 \\) per hour of bulidozer operation. b. Determine the net present value of the investment, assuming that the desired rate of return is \20. 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. c. Should Briggs Excavation invest in the bulldozer, based on this analysis? \\( \\checkmark \\), because the bulldozer cost is \\( \\checkmark \\) the present value of the cash flows at the minimum desired rote of return of \20. d. Determin 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. hours
