(An LP model for the blending problem) The Exxoff-Still Company must decide how different components of the raw materials are blended for their gasoline production. The characteristics of their two gasoline products are listed below: Gasoline Vaper Pressure Octane Number Selling price ($/barrel) Regular ≤7 ≥80 10 Premium ≤6 ≥100 12 The characteristics of the raw materials from which the gasoline can be blended are shown below: Raw Materials Vaper Pressure Octane Number Availability (barrels) Cat Gas 8 83 2700 IsoIso Gas 20 109 1350 Brady Gas 4 74 4100 The vapor pressure and octane number of a blend is simply the weighted average of the corre- sponding characteristics of its components (weighted by their proportion in the blend). (a) Please formulate a linear programming model to determine how different components of the raw materials are blended for their gasoline production to maximize Exxoff-Still’s total rev- enue.

Question
(An LP model for the blending problem) The Exxoff-Still Company must decide
how different components of the raw materials are blended for their gasoline production. The
characteristics of their two gasoline products are listed below:
Gasoline Vaper Pressure Octane Number Selling price ($/barrel)
Regular ≤7 ≥80 10
Premium ≤6 ≥100 12
The characteristics of the raw materials from which the gasoline can be blended are shown below:
Raw Materials Vaper Pressure Octane Number Availability (barrels)
Cat Gas 8 83 2700
IsoIso Gas 20 109 1350
Brady Gas 4 74 4100
The vapor pressure and octane number of a blend is simply the weighted average of the corre-
sponding characteristics of its components (weighted by their proportion in the blend).
(a) Please formulate a linear programming model to determine how different components of the
raw materials are blended for their gasoline production to maximize Exxoff-Still’s total rev-
enue. Be sure to clearly define all decision variables and explain the objective and constraints
of your model.
(b) Solve this problem using Jupyter notebook. (Note: I’ve provided a starting point for you, see
