To order the friends by the amount of money they have saved, we first compare their savings:
- Sami: $41.79
- Charlotte: $38.91
- Celeste: $41.68
Now we can list them from least to greatest:
- Charlotte: $38.91 (least)
- Celeste: $41.68
- Sami: $41.79 (greatest)
The correct order from least amount saved to greatest is:
Charlotte, Celeste, Sami.
So the first response is the correct choice.
