Priorto commencing doing calculations in order to determine the bestalternative, it is critical for Rob to consider the followingfactors the useful life of a new ambulance, the cost of new tiresand new fuel pump, useful life of the repaired ambulance, cost ofcapital, federal and state income tax rate, and all the conditions oflease including any hidden charges.

Thebest alternative would be purchasing a new ambulance. Purchasing of anew ambulance may seem to be costly in the short run, but will beless expensive at long run.
