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

### Instruction:
Owen bought 12 boxes of face masks that cost $9 per box. Each box has 50 pieces of masks. He repacked 6 of these boxes and sold them for $5 per 25 pieces. He sold the remaining 300 face masks in baggies at the rate of 10 pieces of mask for $3. How much profit did he make?

### Response:
 Owen alitumia $9 x 12 = $<<9*12=108>>108.
Alipata barakoa 300 kutoka kwenye masanduku 6.
Kuna seti 300/25 = <<300/25=12>>12 za barakoa.
Hivyo, Owen alipata $5 x 12 = $<<5*12=60>>60 kwa kuzipanga upya.
Pia, aliuza baggies 30.
Hivyo, Owen alipata $3 x 30 = $<<3*30=90>>90 kwa kuuza barakoa kwenye baggies.
Hivyo, jumla ya mapato yake ilikuwa $90 + $60 = $<<90+60=150>>150.
Hivyo, faida yake ilikuwa $150 - $108 = $<<150-108=42>>42.
