An animal breeder can buy four types of food for Vietnamese pot-bellied pigs. Each case of Brand A contains 35 units of fiber, 40 units of protein, and 40 units of fat. Each case of Brand B contains 70 units of fiber, 50 units of protein, and 30 units of fat. Each case of Brand C contains 175 units of fiber, 110 units of protein, and 60 units of fat. Each case of Brand D contains 140 units of fiber, 100 units of protein, and 50 units of fat. How many cases of each brand should the breeder mix together to obtain a food that provides 2450 units of fiber, 1630 units of protein, and 930 units of fat? Let x represent the number of cases of Brand A, y represent the number of cases of Brand B, z represent the number of cases of Brand C, and w represent be the number of cases of Brand D. There are four ways in which the breeder can mix brands to obtain a food that provides 2450 units of fiber, 1630 units of protein, and 930 units of fat. If w = 0, the solution is (O.I.I, 0).
