.) rina needs at least 48 units of protein, 60 units of carbohydrates, and 50 units of fat each month. from each kilogram of food a, she receives 2 units of protein, 4 units of carbohydrates, and 5 units of fats. food b contains 3 units of protein, 3 units of carbohydrates, and 2 units of fats. if food a costs php110 per kilogram and food b costs php 90 per kilogram. how many kilograms of each food should sofia buy each month to keep costs at a minimum?
for x kg of A and y kg of B, you want to minimize
p = 100x + 90y
subject to the conditions that
2x+3y >= 46
4x+3y >= 60
5x+2y >= 50
Now graph the region and select the vertex which minimizes p
