Exercising causes an athlete’s body to lose potassium, and it is important to replenish this nutrient after a race.

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?

How can you find how many more grams of potassium the athlete needs to reach the recommended amount?

Answer 1

To solve this problem, I would first calculate the total amount of potassium the athlete consumed from the banana and the orange juice. Then, I would subtract that total from the recommended daily intake of potassium to find out how much more she needs.

Here are the steps in detail:

1. **Calculate the total potassium intake**:
- Potassium from the banana: 0.54 grams
- Potassium from the orange juice: 0.372 grams
- Total potassium intake = 0.54 grams + 0.372 grams

2. **Determine the recommended daily intake**:
- Recommended potassium intake = 4.5 grams

3. **Calculate the remaining potassium needed**:
- Remaining potassium needed = Recommended intake - Total potassium intake

Now, let's do the math:

1. Total potassium intake = 0.54 + 0.372 = 0.912 grams
2. Remaining potassium needed = 4.5 - 0.912 = 3.588 grams

Therefore, the athlete needs **3.588 grams more** of potassium to reach the recommended amount.
