A manufacturer of textile dyes can use two different processing routings for a particular type of dye.
Routing 1 uses drying press A, and routing 2 uses drying press B. Both routings require the same mixing v
to blend chemicals for the dye before drying. The following table shows the time requirements and

Each kilogram of dye processed on routing 1 uses 20 titers of chemicals, whereas each kilogram of dye
processed on routing 2 uses only 15 liters. The difference results from differing yield rates of the drying
presses. Consequently, the profit per kilogram processed on routing 1 is $50 and on routing 2 Is $65. A
