a Question: Fast Courier is a transport company located in Kansas that specializes in door-to-door deliveries. The company owns a fleet of 14 vans and turns to third parties for hiring vans in case the service demand exceeds the fleet capacity.

Assuming that CF = $350, CV = $150 and CH = $ 800, find the optimum number of vans. a Question: Fast Courier is a transport company located in Kansas that specializes in door-to-door deliveries.
