The Sheila Cabot Construction Company (SCCC) is building a local stadium. They need an office at the stadium site. SCCC can build the office themselves with material costing $50,000 and labor costs of $13,000. When the company takes apart the building at the end of the project, 20% of the material would be reusable. Alternatively, SCCC can rent a pre-fabricated building at a cost of $1000 per month with no set-up or dismantling costs. It will benefit SCCC to build the office if it expects the stadium project to exceed
a) 36 months
b) 50 months
c) 53 months
d) 63 months
