A contractor must choose between buying or renting a crane for the duration of a 5 year construction project. The contractor uses an MARR of 8%. The crane costs $590,000 and can be sold for $350,000 after 5 years. The cost to operate and maintain the crane is $230,000 per year. Renting the crane costs $340,000 per year including all operating and maintenance costs.
