Softa [21]

Answer:

She takes 11 grams more protein for breakfast than for a snack.

Step-by-step explanation:

Consider the provided information.

Gina had a scrambled egg and a cup of low-fat milk for breakfast.

She had an oat bran muffin for a morning snack.

First round up the numbers as shown below:

Food Protein (in grams) 1 scrambled egg 6.71 ≈ 7

1 cup shredded wheat cereal 5.51 ≈ 6

1 oat bran muffin 3.98 ≈ 4

1 cup low-fat milk 8.22 ≈ 8

Protein in Breakfast = a scrambled egg + a cup of low-fat milk

Protein in Breakfast = 7+8 = 15

Morning snack she had an oat bran muffin.

Protein in Morning snack = 4

Now we need to find how many more grams of protein did Gina have for breakfast than for a snack?

So subtract them as shown below:

15-4 = 11

Hence, she takes 11 grams more protein for breakfast than for a snack.
