A Company X invests $300,000 in a new product. If the payback period is 5 years, find the product return cash flow per year.

(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…
