Southern Oil Company produces two grades of gasoline: regular and premium. The profit contributions are $0.30 per gallon for regular gasoline and $0.50 per gallon for premium gasoline. Each gallon of regular gasoline contains 0.3 gallons of grade A crude oil, and each gallon of premium gasoline contains 0.6 gallons of grade A crude oil. For the next production period, Southern has 18,000 gallons of grade A crude oil available. The refinery used to produce the gasolines has a production capacity of 50,000 gallons for the next production period. Southern Oil's distributors have indicated that demand for the premium gasoline for the next production period will be at most 20,000 gallons. a. Formulate a linear programming model that can be used to determine the number of gallons of regular gasoline and the number of gallons of premium gasoline that should be produced in order to maximize total profit contribution. If required, round your answers to two decimal places. If your answer is zero, enter"0". If the constant is "1" it must be entered in the box. Let R = number of gallons of regular gasoline produced P = number of gallons of premium gasoline produced R C P _ Grade A crude oil available Production capacity Demand for premium RPC b. What is the optimal solution? Gallons of regular gasoline Gallons of premium gasoline Total profit contribution TULLI PIOIL COLLIDULUI c. What are the values and interpretations of the slack variables? If an amount is zero, enter"0" Value of Slack Variable Constraint Interpretation d. What are the binding constraints?
