Answer:
net cash flows = $37,500 per year
Explanation:
initial investment $125,000
operate 1,000 hours per year for 5 years
price per hour $90
direct labor costs $30 per hour
direct materials (fuel) $15 per hour
annual maintenance $7,500
the annual cash flows from operating the bulldozer = [($90 (price per hour) - $45 (total variable costs per hour) x 1,000 hours] - $7,500 (annual maintenance cost) = $45,000 - $7,500 = $37,500 per year
the cash flows should be the same for years 1 through 5.
