Below is an instruction that describes a task. Write a response that appropriately completes the request in French. Please answer in French.

### Instruction:
 Isabella has $45 more than Sam but only $15 more than Giselle. If Giselle has $120, calculate the total amount of money each shopper will receive if Isabella, Sam, and Giselle donate the money to three shoppers at their local town's supermarket who then decides to share it equally.


### Response:
 Si Isabella a seulement $15 de plus que Giselle, elle a $120 + $15 = $135
Ensemble, Isabella et Giselle ont $135 + $120 = $<<135+120=255>>255
Isabella a $45 de plus que Sam, ce qui signifie que Sam a $135 - $45 = $<<135-45=90>>90
Le montant total d'argent que les trois acheteurs ont est de $255 + $90 = $<<255+90=345>>345
S'ils donnent l'argent à trois acheteurs du supermarché de leur ville locale qui décident ensuite de le partager également, chaque acheteur recevra $345/3 = $<<345/3=115>>115
