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

### Instruction:
 Jude bought three chairs for his house, all at the same price. He also bought a table that costs $50 and two sets of plates at $20 for each set. After giving the cashier $130, Jude got a $4 change. How much did each of the chairs cost?


### Response:
 Les deux ensembles d'assiettes coûtent $20 x 2 = $<<20*2=40>>40.
Donc, la table et les deux ensembles d'assiettes coûtent $50 + $40 = $90 au total.
Puisque Jude a reçu un changement de $4, alors il a payé un total de $130 - $4 = $<<130-4=126>>126 pour les chaises, la table et les assiettes.
Ainsi, les trois chaises coûtent $126 - $90 = $<<126-90=36>>36.
Donc, chaque chaise coûte $36/3 = $<<36/3=12>>12.
