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

### Instruction:
John plays at the arcade for 3 hours.  He uses $.50 for every 6 minutes.  How much money did he spend, in dollars?

### Response:
 Alikuwapo katika arcade kwa dakika 3*60=<<3*60=180>>180
Hivyo ni 180/6=<<180/6=30>>30 matumizi ya mashine
Hivyo alitumia 30*.5=$<<30*.5=15>>15
