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

### Instruction:
Keaton has a farm of oranges and apples. He can harvest his oranges every 2 months and can sell the harvest for $50.  He can harvest his apples every 3 months and can sell this harvest for $30. How much money can Keaton earn every year?

### Response:
 Keaton anaweza kuvuna machungwa yake mara 6 kwa mwaka kwa kuwa miezi 12/2 = 6.
Hivyo jumla ya pesa anazopata kutokana na machungwa kwa mwaka ni $50 x 6 = $300.
Anaweza kuvuna matofaa yake mara 4 kwa mwaka kwa kuwa miezi 12/3 = 4.
Hivyo jumla ya pesa anazopata kutokana na matofaa kwa mwaka ni $30 x 4 = $120.
Hivyo jumla ya pesa anazopata kutokana na machungwa na matofaa ni $120 + $300 = $420 kwa mwaka.
