i'm having trouble with the following problem:

Suppose Texas, California, and Alaska each produce a million barrels of oil. 800,000 barrels are needed in Chicago at a distance of 1000, 2000, and 3000 miles fro mthe three producers; and 2,200,000 barrels are needed in New England 1500, 3000, and 3700 miles away. If shipments cost one unit for each barrel-mile, what linear program with five equality constraints has to be solved to minimize the shipping cost?

i can't seem to come up with the constraints and im not sure what it means by each "barrel-mile".. can anyone help please?

thanks
