Answer:
Minimum cost and vitamins are achieved at $0.24.
Explanation:
Two equations
8x + 6y = 48
x + 2y = 12
Cost function
C = 0.05x + 0.03y
Minimum cost is $0.24.
which is achieved at 0 ounces of oat and 8 ounces of rice
Vitamin A
8x + 6y - 48
Vitamin B
x + 2y = 12
Put these equations on a graph
C= 0.05 {0} + 0.03 {8}
C= $0.24
Thus the minimum cost and vitamins are achieved at $0.24.
