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 1.5 ounces of silver and twice as much gold.  The silver costs $20 per ounce.  The gold is 50 times more expensive per ounce.  How much does he spend on everything?


### Response:
 Il achète l'argent pour 1.5*20=$<<1.5*20=30>>30
Il achète 1.5*2=<<1.5*2=3>>3 onces d'or
L'or vaut 20*50=$<<20*50=1000>>1000 par once
Donc il dépense 3*1000=$<<3*1000=3000>>3000 sur l'or
Donc au total il dépense 3000+30=$<<3000+30=3030>>3030
