To provide your child with at least 180 calories, at least 120% of the U.S. RDA of vitamin C, and at least 37 grams of carbohydrates, you can do so by serving 2 servings of Gerber Mixed Cereal for Baby, 0 servings of Gerber Mango Tropical Fruit Dessert, and 1 serving of Gerber Apple Banana Juice.
This combination provides a total of 180 calories (2 servings of cereal at 60 calories each + 1 serving of juice at 60 calories), 240% of the U.S. RDA of vitamin C (2 servings of juice at 120% each), and 41 grams of carbohydrates (2 servings of cereal at 11 grams each + 1 serving of juice at 15 grams).
The total cost for this combination would be 11¢ x 2 + 30¢ x 1 = 52¢.
Shadow costs:
- Shadow cost for calories: 52¢ / 180 calories = 0.29¢ per calorie
- Shadow cost for vitamin C: 52¢ / 240% vitamin C = 0.22¢ per % of vitamin C
- Shadow cost for carbohydrates: 52¢ / 41 grams = 1.27¢ per gram of carbohydrates
