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

### Instruction:
John buys 20 hours of music a month.  The average length of a song is 3 minutes.  He buys each song for $.50.  How much does he pay for music a year?

### Response:
 Ananunua dakika 20*60=<<20*60=1200>>1200 za muziki kwa mwezi
Hivyo ni wimbo 1200/3=<<1200/3=400>>400
Hii inamaanisha anapata 400*.5=$<<400*.5=200>>200 kwa mwezi
Hivyo inakuwa 200*12=$<<200*12=2400>>2400 kwa mwaka
