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___
A. subtract 4.5 - 0.372
B. add 0.54 + 0.327 + 4.5
C. add 0.54 + 0.372 and subtract the sum from 4.5
D. subtract 4.5 - 0.54

To determine how many more grams of potassium the athlete needs to reach the recommended amount, we should first calculate the total amount of potassium the athlete has consumed from the banana and the orange juice.
The potassium from the banana is 0.54 grams, and from the orange juice, it is 0.372 grams.
1. Calculate the total potassium consumed:
\( 0.54 + 0.372 = 0.912 \) grams
2. Then, subtract the total potassium consumed from the recommended intake of 4.5 grams to find out how much more she needs:
\( 4.5 - 0.912 \)
Now, regarding the options provided:
A. subtract 4.5 - 0.372 (This does not account for both sources of potassium)
B. add 0.54 + 0.327 + 4.5 (This is incorrect; there should not be a 0.327 and not a need to add 4.5)
C. add 0.54 + 0.372 and subtract the sum from 4.5 (This correctly describes the process to find the remaining potassium needed)
D. subtract 4.5 - 0.54 (This does not account for the potassium from the orange juice)
The correct choice is **C**: add 0.54 + 0.372 and subtract the sum from 4.5.
