Answer:

Gerber mixed cereal for baby 1 servings and Gerber mango tropical fruit dessert 2 servings

Step-by-step explanation:

calories = 60 + 80 + 80 = 220

grams of carbohydrates = 11 + 21 +21 = 53

this is probably easy to guess, but the way to do it it's the following

first see the units you need, for example in 53g

to get that 3 with the numbers you have to sum ( 21, 11) you need to sum 3, 13, etc, numbers (because you only have ones)

then you look at the tens in 53, and you finish to figure out that you can only sum 3 numbers, and that, to get that 5, they need to be two 21 and one 11.

that means the only way to get that amount of carbs is with 1 serving of Gerber mixed cereal for babyand and 2 servings of Gerber mango tropical fruit dessert.

Then you need to check that the amount of calories in that servings it's the required too. 60 + 80 + 80 = 220
