[Question]A merchant bought 15 keyboards and 25 printers for a total of $2050. If a keyboard costs $20, how much does a printer cost?
[Answer]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. The answer is 70.

[Question]A man decides to try and do everything off his bucket list while he is still young and fit enough to finish it all. One of his goals was to climb the seven summits. He realizes first he has to get in shape to do it and it takes him 2 years of working out to get healthy enough to take up mountain climbing. He then spends twice that long learning how to be a technically proficient mountain climber. After that he starts with the simplest mountain on the list and climbs them all. He spends 5 months climbing each mountain. After that he takes 13 months learning to dive and dives through all the caves he wants in 2 years. How much time did it take to get through all these goals?
[Answer]He spent 2 * 2 = 4 years learning to climb. He spends 5 * 7 = 35 months climbing all 7 mountains. After a 13 month break, he starts diving so that is 35 + 13 = 48 months. That means it is 48 / 12 = 4 years. So in total it all took 2 + 4 + 4 + 2 = 12 years. The answer is 12.

[Question]Jane's goal is to exercise 1 hour a day, 5 days a week. If she hits her goal weekly for 8 weeks, how many hours has Jane exercised?
