Question

For middle-school students, the recommended amount of potassium intake is 4.5 grams per day. If a student athlete eats a banana containing 0.54 grams of potassium, and drinks 6 ounces of orange juice containing 0.372 grams of potassium, how many more grams of potassium does she need?

Answer 1

After consuming a banana and orange juice, the student athlete needs an additional 3.588 grams of potassium to meet the daily recommended intake of 4.5 grams.

Step-by-step explanation:

For middle-school students, the recommended amount of potassium intake is 4.5 grams per day. If a student athlete has consumed a banana with 0.54 grams of potassium and 6 ounces of orange juice with 0.372 grams of potassium, we need to calculate the total potassium intake from these two sources and subtract it from the recommended intake.

First, we add the potassium from the banana and the orange juice:
0.54 grams (banana) + 0.372 grams (orange juice) = 0.912 grams

Now, we need to find out how much more potassium is needed to meet the daily recommendation:
4.5 grams (recommended) - 0.912 grams (consumed) = 3.588 grams

Therefore, the student athlete needs 3.588 more grams of potassium to meet the daily recommended intake.
