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

### Instruction:
Jan buys 5 dozen roses.  Each rose cost $6.  Since he bought so many he only needs to pay 80%.  How much did he pay?

### Response:
He got 5*12=<<5*12=60>>60 roses
So the cost was 6*60=$<<6*60=360>>360
So he needs to pay 360*.8=$<<360*.8=288>>288
#### 288
