Darcy Roofing is faced with a decision. The company relies very heavily on the use of its 60-foot extension lift for work on large homes and commercial properties. Last year, Darcy Roofing spent $60,000 refurbishing the lift. It has just been determined that another $50,000 of repair work is required. Alternatively, it has found a newer used lift that is for sale for $170,000. The company estimates that both lifts would have useful lives of 5 years. The new lift is more efficient and thus would reduce operating expenses from $90,000 to $60,000 each year. Darcy Roofing could also rent out the new lift for about $10,000 per year. The old lift is not suitable for rental. The old lift could currently be sold for $15,000 if the new lift is purchased. The new lift and old lift are estimated to have salvage values of zero if used for another 6 years. 

Prepare an incremental analysis showing whether the company should repair or replace the equipment.
