Question: Jenny likes to play board games with her friends. She likes to play against her friend Mark the most, as she's played him 10 times and Mark has only won once. She doesn't like playing Jill, as she's played her twice as many times as she's played Mark and Jill has won 75% of them. How many times in total has Jenny won board games with her two friends?
Answer: Jenny has played Mark 10 times, and since mark has only won once she's had 10 - 1 = 9 wins. Jenny has played Jill twice as many times as Mark, so they've played 10 * 2 = 20 games. Of the 20 games Jenny and Jill have played, Jill has won 75% of them so she's had 20 * .75 = 15 wins. If Jill has won 15 games, that means Jenny won 20 - 15 = 5 games. For Jenny's total wins, her wins against Mark and Jill are added together for 5 + 9 = 14 wins. The answer is 14.

Question: Barry has $10.00 worth of dimes. His little brother, Dan has half that amount but finds 2 more dimes on his way home from school. How many dimes does Dan have?
Answer: Dimes are worth $0.10 and Barry has $10.00 worth of dimes so he has 10 / .10 = 100 dimes. Dan has half the amount of dimes as Barry so Dan has 100 / 2 = 50 dimes. Dan finds 2 more dimes on his way home so he now has 50 + 2 = 52 dimes. The answer is 52.

Question: Mary is chopping up some old furniture to make firewood. Chairs make 6 sticks of wood, tables make 9 sticks of wood, and stools make 2 sticks of wood. Mary needs to burn 5 sticks of wood per hour to stay warm. If Mary chops up 18 chairs, 6 tables and 4 stools, how many hours can she keep warm?
Answer: First find the total sticks from the chairs: 6 sticks / chair * 18 chairs = 108 sticks. Then find the total sticks from the tables: 9 sticks / table * 6 tables = 54 sticks. Then find the total sticks from the stools: 2 sticks / table * 4 stools = 8 sticks. Then add up the total number of sticks she gets: 108 sticks + 54 sticks + 8 sticks = 170 sticks. Then divide the total number of sticks by the number of sticks she burns per hour to find the total number of hours she can keep warm: 170 sticks / 5 sticks / hour = 34 hours. The answer is 34.

Question: Mike has to get an x-ray and an MRI. The x-ray is $250 and the MRI is triple that cost. Insurance covers 80%. How much did he pay?
Answer:
The MRI cost 250 * 3 = $750. So between the two things he pays 250 + 750 = $1000. Insurance covered 1000 * .8 = $800. So he had to pay 1000 - 800 = $200. The answer is 200.
