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

### Instruction:
 Cassy packs 12 jars of jam in 10 boxes while she packs 10 jars of jam in 30 boxes. If she has 500 jars of jams, how many jars of jam will she have left when all the boxes are full?


### Response:
 Cassy packs 12 jars of jam in 10 boxes while she packs 10 jars of jam in 30 boxes.

Donc, 12 pots de confiture = 10 boîtes

10 pots de confiture = 30 boîtes

Ainsi, 1 pot de confiture = 3 boîtes

Par conséquent, 500 pots de confiture = 500 * 3 = 1500 boîtes

Donc, 1500 boîtes - 1000 boîtes = 500 boîtes restantes.
