A merchant bought 15 keyboards and 25 printers for a total of $2050. If a keyboard costs $20, how much does a printer cost?
Please answer and provide answer explanation.
70
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.

.

Thus, the answer is 70
