Osborne Excavation Company is planning an investment of $78,000 for a bulldozer. The bulldozer is expected to operate for 1,000 hours per year for six years. Customers will be charged $105 per hour for bulldozer work. The bulldozer operator costs $31 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 $41 per hour of bulldozer operation.
