Nan uses two different biofuel mixtures in her diesel vehicle. both mixtures contain 20% ultra low sulfur diesel. mix 1 also contains 30% soybean oil and 50% waste cooking oil; mix 2 also contains 20% soybean oil and 60% animal fat. mix 1 generates 40 co emissions per gallon; mix 2 generates 74 co emissions per gallon. (note: units are shifted and scaled from actual units of grams per gallon for the purposes of this example.) nan wants to minimize the co emissions in 10 total gallons of fuel used in her vehicle. she has available 10 gallons of soybean oil, 4 gallons of waste cooking oil, and 5 gallons of animal fat. assuming there is no limit on ultra low sulfur diesel, formulate an lp model to determine how much of biodiesel mixtures 1 and 2 nan should use in her vehicle?
