Question: Gary bought his first used car for $6,000. Gary borrowed the money from his dad who said he could pay him back the full amount over 5 years. Gary decided he would pay his dad back the full amount in 2 years. How much more is Gary spending per month to pay the loan off in 2 years instead of 5?
Answer: A full year has 12 months. So 2 years is 2 * 12 = 24 months. The loan amount is $6,000 that he will repay in 24 months so 6000 / 24 = $250 per month. If he paid his dad back in 5 years that 5 * 12 = 60 months. $6,000 loan spread out over 60 months is 6000 / 60 = $100 per month. To pay it off in 2 years instead of 5, Gary is paying 250 - 100 = $150 more per month. The answer is 150.
[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.
Q: John eats a bag of chips for dinner and then eats twice as many after dinner. How many bags of chips did he eat?

Question: There are 120 cards in a box. If 2/5 of the cards are red, exactly 5/9 of the remainder are black, and the rest are green, calculate the number of green cards in the box?
Answer: The number of red cards in the box, 2 / 5 of the total number, is 2 / 5 * 120 = 48. The number of cards that are not red is 120 - 48 = 72. If 5 / 9 of the remaining cards are black, then there are 5 / 9 * 72 = 40 black cards in the box. If the remaining cards are green, then there are 72 - 40 = 32 green cards in the box. The answer is 32.
[Question]Ralph is going to practice playing tennis with a tennis ball machine that shoots out tennis balls for Ralph to hit. He loads up the machine with 175 tennis balls to start with. Out of the first 100 balls, he manages to hit 2/5 of them. Of the next 75 tennis balls, he manages to hit 1/3 of them. Out of all the tennis balls, how many did Ralph not hit?
[Answer]Out of the first 100 balls, Ralph was able to hit 2 / 5 of them and not able to hit 3 / 5 of them, 3 / 5 x 100 = 60 tennis balls Ralph didn't hit. Out of the next 75 balls, Ralph was able to hit 1 / 3 of them and not able to hit 2 / 3 of them, 2 / 3 x 75 = 50 tennis balls that Ralph didn't hit. Combined, Ralph was not able to hit 60 + 50 = 110 tennis balls Ralph didn't hit. The answer is 110.
[Question]While preparing for a meeting, Bill fills Dixie cups with water from out of a water cooler. The water cooler initially contains 3 gallons of water, and each Dixie cup holds 6 ounces of water. If Bill fills one cup of water per each meeting chair, and there are 5 rows of meeting chairs with 10 chairs in each row, then how many ounces of water will be left in the cooler after all cups have been are filled? (There are 128 ounces in a gallon.)
[Answer]
First find the total number of ounces in the water cooler: 3 gallons * 128 ounces / gallon = 384 ounces. Then find the total number of dixie cups Bill pours: 5 rows * 10 chairs / row = 50 chairs. Then find the total number ounces Bill pours: 50 attendees * 6 ounces / attendee = 300 ounces. Then subtract the amount of water Bill pours from the cooler from the initial amount to find the final amount: 384 ounces - 300 ounces = 84 ounces. The answer is 84.
