Briggs Excavation Company is planning an investment of $132,000 for a bulldozer. The bulldozer is expected to operate for 1,500 hours per year for five years. Customers will be charged $110 per hour for bulldozer work. The bulldozer operator costs $28 per hour in wages and benefits. The bulldozer is expected to require annual maintenance costing $8,000. The bulldozer uses fuel that is expected to cost $46 per hour of bulldozer operation.
