### Instruction:
A merchant bought 15 keyboards and 25 printers for a total of $2050. If a keyboard costs $20, how much does a printer cost?

### Response:
 Jumla ya gharama za keyboards ni keyboards 15 * $20/keyboard = $<<15*20=300>>300.
Jumla ya gharama za printers ni $2050 - $300 = $<<2050-300=1750>>1750.
Gharama ya printer moja ni $1750 / 25 printers = $<<1750/25=70>>70.
