Math Problem Statement
An animal breeder can buy four types of food for Vietnamese pot-bellied pigs. Each case of Brand A contains 2525 units of fiber, 3030 units of protein, and 3030 units of fat. Each case of Brand B contains 100100 units of fiber, 9090 units of protein, and 7070 units of fat. Each case of Brand C contains 175175 units of fiber, 150150 units of protein, and 130130 units of fat. Each case of Brand D contains 300300 units of fiber, 270270 units of protein, and 190190 units of fat. How many cases of each should the breeder mix to obtain a food that provides 29002900 units of fiber, 25502550 units of protein, and 20902090 units of fat?
