An animal breeder can buy four types of food for Vietnamese pot-bellied pigs. Each case of Brand A contains 25 units of fiber, 40 units of protein, and 40 units of fat. Each case of Brand B contains 50 units of fiber, 50 units of protein, and 30 units of fat. Each case of Brand C contains 75 units of fiber, 60 units of protein, and 30 units of fat. Each case of Brand D contains 100 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 1275 units of fiber, 1140 units of protein, and 630 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 1275 units of fiber, 1140 units of protein, and 630 units of fot. 1 w = 0, the solution is (0.0.0.0).
