MAG Industrial needs 1000 square meters of storage space. Purchasing land for $80,000 and then erecting a temporary metal building at $70 per square meter is one option. The president hopes to sell the land for $100,000 and the building for

$20,000 after 3 years. Another option is to lease space for $30 per square meter per year payable at the beginning of each year. The MARR is 20%.

Perform a present worth analysis of the building and leasing alternatives to determine the sensitivity of the decision if the construction cost decreases by 10% to $63 per square meter and the lease cost remains at $30 per square meter per year.
