The liquid portion of a diet is to provide at least 300 calories, 36 units of vitamin A, and 90 units of vitamin C daily. A cup of Gatorade provides 60 calories, 12 units of vitamin A, and 10 units of vitamin C. A cup of Body Armour provides 60 calories, 6 units of vitamin A, and 30 units of vitamin C. Now, suppose Gatorade costs $0.12 per cup and Body Armour costs $0.15 per cup. How many cups of each drink should be consumed each day to minimize the cost and still meet the stated daily requirements?
