Answer:
30 units of Food A and 45 units of Food B are to be purchased to keep costs at the minimum $105.
Explanation:
X = Amount of food A
Y = Amount of food B
Z= 2X+Y..... minimum cost equation

30X + 20Y > 1800 ...................Minerals.......(2)
10X + 40Y > 1200 .................Calories ..........(3)
X > 0
y > 0
X=30 and Y = 45
Z= 2(30) + 45 = $105
