ABC Restaurant has an ice-cream counter where it sells two main products, ice cream and frozen yogurt. The restaurant makes a gallon ice cream and yogurt each day, and store has enough freezer space for 115 gallons total of both products. A gallon of frozen yogurt costs $0.75 and a gallon of ice cream costs $0.93, and the restaurant has budget of $90 for these products. The manager estimates that the store sells at least twice as much ice cream as frozen yogurt. Profit per gallon of ice cream is $4.15, and profit per gallon is $3.60. Formulate a linear programming model for this problem.
