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

### Instruction:
 John has 25 horses. He feeds each horse twice a day and feeds them 20 pounds of food at each feeding. He buys half ton bags of food. How many of those will he have to buy in 60 days?


### Response:
 Il utilise 20*2=40 livres de nourriture par cheval par jour. Donc, il utilise 40*25=1000 livres de nourriture par jour. Cela signifie qu'en 60 jours, il utilise 60*1000=60000 livres de nourriture. Chaque sac de nourriture pèse 2000*.5=1000 livres. Donc, il doit acheter 60000/1000=60 sacs de nourriture.
