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

### Instruction:
 Aaron has four times as many cows as does Matthews. Together, they have 30 more cows than Marovich. If Matthews has 60 cows, how many cows do the three have altogether?


### Response:
 Si Matthews a 60 vaches, Aaron a 4*60=240 vaches.
Ensemble, Aaron et Matthews ont 240+60=<<240+60=300>>300 vaches.
Puisque Marovich a 30 vaches de moins que le nombre total de vaches qu'Aaron et Matthews ont, Marovich a 300-30=270 vaches.
Au total, les trois ont 270+300=<<270+300=570>>570 vaches.
