An animal feed to be mixed from soybean meal and oats must contain at least 120 lb of protein, 24 lb of fat, and 10 lb of mineral ash.

Each sack of soybeans costs $ 15 and contains 50 lb of protein, 8 lb of fat, and 5 lb of mineral ash.

Each sack of oats costs $5 and contains 15 lb of protein, 5 lb of fat, and 1 lb of mineral ash.

How many sacks of each should be used to satisfy the minimum requirements at minimum cost?

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

r and t.

both are 64 degrees.
