### Instruction:
Tas and his friends put up a t-shirt for sale. They ended up selling 200 t-shirts in 25 minutes. Half of the shirts were black and cost $30, while the other half were white and cost $25. How much money did they make per minute during the sale?

### Response:
 Mapato jumla kutoka kwa fulana nyeusi yalikuwa 100 * $30 = $3000.
Mapato jumla kutoka kwa fulana nyeupe yalikuwa 100 * $25 = $2500.
Mapato jumla kutoka kwa fulana zote zilizouzwa yalikuwa $3000 + $2500 = $5500.
Kiasi cha pesa walichopata kwa dakika kilikuwa $5500 / 25 dakika = $220 kwa dakika.
