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

### Instruction:
 James buys 3 dirt bikes for $150 each and 4 off-road vehicles for $300 each.  It also cost him $25 to register each of these.  How much did he pay for everything?


### Response:
 Il a payé 3*150 = 450 $ pour les motos tout-terrain
Il a payé 4*300 = 1200 $ pour les véhicules tout-terrain
Il devait enregistrer 3+4 = 7 véhicules
Donc l'enregistrement coûte 25*7 = 175 $
Donc le coût total de tout était de 450+1200+175 = 1825 $
