Bay Oil produces two types of fuels (regular and super) by mixing three ingredients.

Bay Oil produces two types of fuels (regular and super) by mixing three ingredients.

The major distinguishing feature of the two products is the octane level required. Regular

fuel must have a minimum octane level of 90 while super must have a level of at

least 100. The cost per barrel, octane levels, and available amounts (in barrels) for the

upcoming two-week period are shown in the following table. Likewise, the maximum

demand for each end product and the revenue generated per barrel are shown.
