Response to the following problem:
Your company has purchased a new excavator for $210,000. The track hoe can be billed out at $180.00 per hour, has an hourly operation cost of $104.00, and has a useful life of six years. At the end of six years the track hoe has a salvage value of $35,000. The operator cost is $36.00 per hour.
Using a MARR of 25%, what is the minimum number of billable hours each year in order for your company to break even?
