Answer:

30 units of Food A and 45 units of Food B are to be purchased to keep costs at the minimum $105.

50X + 20Y > 2400 .................Vitamins .......(1)

30X + 20Y > 1800 ...................Minerals.......(2)

10X + 40Y > 1200 .................Calories ..........(3)

X=30  and Y = 45

Z= 2(30) + 45 = $105
