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

### Instruction:
 Bernie loves eating chocolate. He buys two chocolates every week at the local store. One chocolate costs him $3. In a different store, there is a long-term promotion, during which each chocolate costs only $2. How much would Bernie save in three weeks, if he would buy his chocolates in this store instead of his local one?


### Response:
 Bernie achète deux chocolats chaque semaine, donc pendant trois semaines, il achèterait 3 * 2 = <<3*2=6>>6 chocolats.
Le prix d'un chocolat dans le magasin local est de $3, donc Bernie paie 3 * 6 = $<<3*6=18>>18 pour six chocolats.
Le prix d'un chocolat dans le magasin différent est de $2, donc Bernie paierait 2 * 6 = $<<2*6=12>>12 pour les mêmes chocolats là-bas.
Donc Bernie serait capable d'économiser 18 - 12 = $<<18-12=6>>6.
