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

### Instruction:
John cuts his grass to 2 inches.  It grows .5 inches per month.  When it gets to 4 inches he cuts it back down to 2 inches.  It cost $100 to get his grass cut.  How much does he pay per year?

### Response:
 Anapunguza nyasi zake kwa inchi 4-2=2.
Hii inachukua miezi 2/0.5=4.
Hivyo anamlipa kila baada ya miezi 4.
Hii inamaanisha anamlipa mara 12/4=3 kwa mwaka.
Hivyo anamlipa $3*100=$300 kwa mwaka.
