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

### Instruction:
Joe likes to play video games and he normally spends $50 a month on video games.  Joe also sells his games for $30 each once he is done playing them. If he starts with $240, how many months can he buy games at $50 and sell them at $30 before he is out of money?

### Response:
 Joe anaweza kununua mchezo kwa $50 na kuuza kwa $30, kwa hivyo anapoteza $50 - $30 = $<<50-30=20>>20 kila mwezi anaponunua na kuuza mchezo.
Joe anaanza na $240 na ananunua mchezo na kuuza mchezo anapoteza $20 kwa mwezi, kwa hivyo itachukua $240 / ($50 - $30) = 12 miezi mpaka atakapokosa pesa.
