Mr. Smith decides to feed his pet Doerman pinscher a combination of two dog foods.  Each can of brand A contains 3 units of protein, 1 unit of carbohydrates, and 2 units of fat and costs 60 cents.  Each can of brand B contains 1 unit of protein, 1 unit of carbohydrates, and 4 units of fat and costs 40 cents.  Mr. Smith feels that each day his dog should have at least 6 units of protein, 4 units of carbohydrates, and 12 units of fat.  How many cans of each dog food should he give to his dog each day to provide the minimum requirements at the least cost?

6 cans of brand A cost $3.60 (6*.6) so the correct answer should be (1,3) 1 can A and 3 cans B for $1.80.
