An oil refinery in Tulsa sells 25% of its production to a Chicago distributor, 40% to a Dallas distributor,
and 35% to an Atlanta distributor. Another refinery in New Orleans sells 35% of its production to the
Chicago distributor, 50% to the Dallas distributor, and 15% to the Atlanta distributor. A third refinery in
Ardmore sells the same distributors 40 % , 30 % , and 30 of its production. The three distributors
received 187, 400, 225, 400, and 137, 200 gallons of oil, respectively. Set up the system and solve.
Let z, y, and z represent the gallons of oil produced at Tulsa, New Orleans, and Ardmore, respectively.
Write the equation that represents the number of gallons of oil that Chicago received.
