Bindley Corporation has a one-year contract to supply motors for all washing machines produced by Rinso Ltd. Rinso manufactures the washers at four locations around the country: New York City, Fort Worth, San Diego, and Minneapolis. Plans call for the following numbers of washing machines to be produced at each location:

New York City	75,000
Fort Worth	59,000
San Diego	77,000
Minneapolis	60,000

Bindley has three plants that can produce the motors. The plants and production capacities are

Boulder	51,000
Macon	160,000
Gary	70,000

Due to varying production and transportation costs, the profit Bindley earns on each 1,000 units depends on where they were produced and where they were shipped. The following table gives the accounting department estimates of the dollar profit per unit. (Shipment will be made in lots of 1,000.)

	SHIPPED TO
PRODUCED AT	NEW YORK CITY	FORT WORTH	SAN DIEGO	MINNEAPOLIS
Boulder	20	14	18	14
Macon	25	28	22	13
Gary	8	10	20	30

Given profit maximization as a criterion, Bindley would like to determine how many motors should be produced at each plant and how many motors should be shipped from each plant to each destination.
