An animal breeder can buy four types of food for Vietnamese pot-bellied pigs. Each case of Brand A contains 25 units of fiber, 30 units of protein, and 30 units of fat. Each case of Brand B contains 100 units of fiber, 80 units of protein, and 80 units of fat. Each case of Brand C contains 275 units of fiber, 210 units of protein, and 230 units of fat. Each case of Brand D contains 100 units of fiber, 80 units of protein, and 60 units of fat. How many cases of each brand should the breeder mix to obtain a food that provides 3675 units of fiber, 2850 units of protein, and 3030 units of fat? Let x represent the number of cases of Brand A, y represents the number of cases of Brand B, z represents the number of cases of Brand C, and w represent the number of cases of Brand D. There are four ways in which the breeder can mix brands to obtain a food that provides 3675 units of fiber, 2850 units of protein, and 3030 units of fat. If w = 0, the solution is (-, -, -, 0)

Question
An animal breeder can buy four types of food for Vietnamese pot-bellied pigs. Each case of Brand A contains 25 units of fiber, 30 units of protein, and 30 units of fat. Each case of Brand B contains 100 units of fiber, 80 units of protein, and 80 units of fat. Each case of Brand C contains 275 units of fiber, 210 units of protein, and 230 units of fat. Each case of Brand D contains 100 units of fiber, 80 units of protein, and 60 units of fat. How many cases of each brand should the breeder mix to obtain a food that provides 3675 units of fiber, 2850 units of protein, and 3030 units of fat?

Let x represent the number of cases of Brand A, y represents the number of cases of Brand B, z represents the number of cases of Brand C, and w represent the number of cases of Brand D. There are four ways in which the breeder can mix brands to obtain a food that provides 3675 units of fiber, 2850 units of protein, and 3030 units of fat.

If w = 0, the solution is (-, -, -, 0)
