Come up with a question and stream of consciousness reasoning that would justify this answer: 70
The question is: A merchant bought 15 keyboards and 25 printers for a total of $2050. If a keyboard costs $20, how much does a printer cost?
Stream of consciousness: 15 keyboards at $20 per keyboard cost a total of 15 * $20 = $300. The total cost of printers and keyboards is $2050 so 25 printers cost $2050 - $300 = $1750. 1 printer cost $1750 / 25 = $70.
