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

### Instruction:
 Mark wants to have a water balloon fight with his friends. He goes to the store to buy balloons and sees that they sell small bags for $4, medium bags for $6 and extra large bags for $12. He has $24 and wants to get the most balloons as possible. If the $4 bags contain 50 balloons, the $6 bags contain 75 balloons and the $12 bags contain 200 balloons, what is the greatest number of balloons he can buy?


### Response:
 Il peut acheter 2 sacs de 12 $ et il lui reste 24 $ - 12 $ - 12 $ = <<24-12-12=0>>0.
Il peut ensuite acheter 6 sacs de 6 $ et il lui reste 0 $ - 6 $ - 6 $ - 6 $ - 6 $ - 6 $ = <<0-6-6-6-6-6=-36>>-36.
Il peut ensuite acheter 9 sacs de 4 $ et il lui reste -36 $ - 4 $ - 4 $ - 4 $ - 4 $ - 4 $ - 4 $ - 4 $ - 4 $ = << -36-4-4-4-4-4-4-4-4=-80>>-80.
Par conséquent, il peut acheter 2 + 6 + 9 = <<2+6+9=17>>17 sacs au total, ce qui contient 200 + 75 + 75 + 75 + 75 + 75 + 50 + 50 + 50 + 50 + 50 + 50 + 50 + 50 + 50 + 50 + 50 = <<200+75+75+75+75+75+50+50+50+50+50+50+50+50+50+50+50=1225>>1225 ballons au total.
