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

### Instruction:
 Chloe alinunua matunda ya parachichi yaliyopakwa chokoleti kwa $50 kwa kizibo. Kisha akawauza kwa $30 kwa nusu kizibo wakati wa sherehe ya siku ya Mama. Chloe atapata faida kiasi gani ikiwa atauza dozeni 50?


### Response:
 Ikiwa Chloe alinunua kwa $50 kwa kizibo, basi nusu kizibo ilimgharimu $50 / 2 = $<<50/2=25>>25.
Hivyo, faida ya Chloe ikiwa aliuza dozeni 50 za matunda ya parachichi yaliyopakwa chokoleti kwa $30 kila moja ni $30 x 50 - $25 x 50 = $500.
