Question 442880: One more I am stuck on, I feel like there is something missing. A person who must meet the requirements of a nutritional program is considering a combination of two foods which are in tubes. Each tube of A contains 4 units of protein, 2 units of carbs, and 2 units of fat and weighs 3 pounds. The requirement is 42 units of protein, 30 units of carbs, and 18 units of fat. How many tubes of each should be used?
