We are charged with selecting from the five projects (shown at left). We do not have enough cash or employees to select all of them, so we will have to select a subset. Our goal is to maximize the expected dollar return while keeping within our available resources (cash and employees).

Suppose we need to ship refrigerators from our plants in Marietta and Minneapolis to our distribution centers in Cleveland, Baltimore, Chicago, and Phoenix. Capacities, demand, and unit shipping costs are shown in the table. Our goal is to meet demand at the lowest total shipping cost.

Maximize 5A -3B +10C subject to: A + B + 3C <= 20 B >= 2 3A - 2B <= 15 A,B,C >= 0

Sheds

type A type B type C

profit 80 84 85 max $ 4,325.00
mach time 2 3 4 200 <= 200
craft time 5 5 3 157 <= 160

A small firm builds three types of garden sheds. Type A requires 2 hours of machine time and 5 hours of craftsman time. Type B requires 3 hours of machine time and 5 hours of craftsman time. Type C requires 4 hours of machine time and 3 hours of craftsman time. Each day there are 200 hours of machine time available and 160 hours of craftsman time. The profit on each type A shed is $80, on each type B shed is $84, and on each type C shed is 85 . How many sheds of each type should we make to maximize the profit?
