Question

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?
To solve this problem, I would ( subtract 4.5 - 0.372, add 0.54 + 0.327 + 4.5, add 0.54 + 0.372 and subtract the Sun from 4.5, subtract 4.5 - 0.54)

Answer 1

To find out how many more grams of potassium the athlete needs to reach the recommended amount, follow these steps:

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

Let's calculate that:
\[
0.54 + 0.372 = 0.912 \text{ grams}
\]

2. **Subtract the total potassium consumed from the recommended amount**:
- Recommended amount of potassium = 4.5 grams
- Potassium needed = Recommended amount - Total potassium consumed
\[
4.5 - 0.912 = 3.588 \text{ grams}
\]

So, the athlete needs **3.588 grams** more potassium to reach the recommended amount of 4.5 grams.

To summarize, the method for finding how many more grams of potassium she needs is:

1. Add the potassium from the banana and the orange juice.
2. Subtract that total from the recommended daily amount of potassium (4.5 grams).
