Hi, i need help with this problem
The contribution to profit from the Brand Y only $12.50 per case compared to $100 per case for private label product Brand X.
The recipe for a case of X is 1 unit of Nutrient, 3 units of Color, 15 units of Flavor and 10 units of Grain.
The recipe for a case of Y is 2 units of Nutrient, 1 unit of Color, 1 unit of Flavor and 1 unit of Grain.
In order to meet government health regulations the manufacturer must use at least 250 units of Flavor.
The other ingredients are in short supply, so you must use no more than 400 units of Nutrient, no more than 500 units of Color, and no more than 600 units of Grain.
