Minimization Problem:

Gerber Mixed Cereal for Baby contains, in each serving, 60 calories and no vitamin C. Each serving of Gerber Mango Tropical Fruit Dessert contains 80 calories and 45% of the US Recommended Daily Allowance (RDA) of vitamin C for infants. Each serving of Gerber Apple Banana juice contains 60 calories and 120% of the US RDA of vitamin C for infants. The cereal costs 10 cents per serving, the dessert costs 53 cents per serving, and the juice costs 27 cents per serving. If you want to provide your child with at least 120 calories and at least 120% of the US RDA of vitamin C, how can you do so at the least cost?
