Final answer:
After subtracting the 9.341 ounces that Marilyn took out from the original 20.682 ounces, she would have 11.341 ounces of tomato soup left.
Step-by-step explanation:
If Marilyn starts with 20.682 ounces of tomato soup and she puts 9.341 ounces of it in a bowl, we need to subtract the amount she took out from the total amount to find out how many ounces she will have left. We perform the subtraction 20.682 ounces - 9.341 ounces.
To solve this, we align the decimal points and subtract:
- 20.682
- - 9.341
- ---------
- 11.341
The correct answer is that Marilyn will have 11.341 ounces of tomato soup left after serving.
