The Shop at Home Network sells various household goods during live TV broadcasts. The company owns several warehouses to hold many of the goods it sells but also leases extra warehouse space when needed. During the next five months the company expects that it will need to lease the following amounts of extra warehouse space:

Month 1 2 3 4 5
Sq. ft. needed 20,000 30,000 40,000 35,000 50,000

At the beginning of any month, the company can lease extra space for one or more months at the following costs:

Lease term (months) 1 2 3 4 5
Cost per sq. ft. leased $55 $95 $130 $155 $185

So, for instance, at the start of month 1 the company can lease as much space as it wants for 4 months at a cost of $155 per square foot. The company wants to know the least costly way of meeting its warehousing needs over the coming 5 months.
