E & T Excavation Company is planning an investment of $222,900 for a bulldozer. The bulldozer is expected to operate for 1,000 hours per year for five years. Customers will be charged $130 per hour for bulldozer work. The bulldozer operator costs $26 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 $34 per hour of bulldozer operation.
