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

### Instruction:
 John buys 2 packs of gum and 3 candy bars. Each stick of gum cost half as much as the candy bar. If the candy bar cost $1.5 each, how much did he pay in total?


### Response:
 Le chewing-gum coûte 1,5 $/2 = 0,75 $ par paquet.
Il a donc payé 0,75 $ x 2 = 1,5 $ pour le chewing-gum.
Il a payé 1,5 $ x 3 = 4,5 $ pour les barres de chocolat.
Donc, au total, il a payé 1,5 $ + 4,5 $ = 6 $.
