Answer:
25
Explanation:
One box contains 8 servings, one serving is a cup and the amount of sodium, potassium, and protein in that one serving is 440 milligrams, 171 milligrams, and 4 grams in that order.
Using this information, multiply all the minerals by 8 to get their total amount in the box.
In the entire box of cereal:
Sodium is 3520 milligrams
Potassium is 1368 milligrams
Protein is 32 grams
And they are all in 8 cups
8 grams of protein is 1/4 of 32 because 32/8 is 4
1/4 in a percentage is 25%
She consumed 25 percent of the box
Hope this helps :)
