Write equations/inequalities for each constraint. Graph the feasible region and find the minimum cost.
A rancher is mixing two types of food Brand x and Brand y. Each serving of the combined brands must include 60 grams of protein & 30 grams of fat.
Protein Fat Cost
Brand x 15 10 0.80
Brand y 20 5 0.50
The rancher doesn’t want to use more than 4 grams of each in the combination.
How much Brand x and Brand y should be mixed together for the perfect blend?
