Q: Isabelle gets a job so she can save enough money to go to a concert with her two brothers. Her ticket costs $20. Her brothers both get the children’s discount, and each of their tickets cost $10. Her brothers have saved $5 between the two of them and Isabelle has saved $5. If her job pays $3 per week, how many weeks must she work to afford the tickets?
A: The tickets for both of her brothers will cost her $10 * 2 = $20. To buy tickets for all of them, it will cost Isabelle $20 + $20 = $40. Between all of them, they have saved a total of $5 + $5 = $10. Since they have already saved $10, she needs to earn an additional $40 - $10 = $30 to afford the tickets. Since she makes $3 per week, it will take her $30 / ($3 / week) = 10 weeks to save enough money for all of the tickets. The answer is 10.
Question: Together 3 friends watched 411 short videos. Kelsey watched 43 more than Ekon. Ekon watched 17 less than Uma. How many videos did Kelsey watch?
Answer: Let U = the number of videos Uma watched. Ekon = U - 17. Kelsey = (U - 17) + 43 = U + 26. U + U - 17 + U + 26 = 411. 3U + 9 = 411. 3U = 402. U = 134. Kelsey = 134 + 26 = 160 videos. Kelsey watched 160 videos. The answer is 160.

Q: Mr Julien's store has 400 marbles remaining after the previous day's sales. Twenty customers came into the store, and each bought 15 marbles. How many marbles remain in the store?
A: If each of the 20 customers bought 15 marbles, then they bought 20 * 15 = 300 marbles in total from Mr Julien's store. The number of marbles remaining in the store is 400 - 300 = 100 marbles. The answer is 100.
Question: Travis is hired to take 638 bowls from the factory to the home goods store. The home goods store will pay the moving company a $100 fee, plus $3 for every bowl that is delivered safely. Travis must pay the home goods store $4 each for any bowls that are lost or broken. If 12 bowls are lost, 15 bowls are broken, and the rest are delivered safely, how much should Travis be paid?
Answer: Travis has lost or broken 12 + 15 = 27 bowls. Travis will need to pay the store 27 x $4 = $108 dollars. Travis has safely taken 638 - 27 = 611 bowls. For this, he will be paid 611 x $3 = $1833 dollars. In total Travis will be paid $1833 + $100 = $1933 dollars. Since Travis has to pay the home goods 108 for the broken and lost bowls, he will end up with $1933 - $108 = $1825. The answer is 1825.
Q: John drinks 2 energy drinks. 1 of them is a 12-ounce drink with 250 grams of caffeine. The second drink is 3 times more caffeinated per ounce but only 2 ounces. He then takes a caffeine pill that has as much caffeine as his 2 drinks combined. How much caffeine did he consume?
A:
The second drink was 2 / 12 = 1 / 6 the size of the first drink. So it had 1 / 6 * 3 = 1 / 2 the caffeine. That means it had 1 / 2 * 250 = 125 grams of caffeine. So the total amount of caffeine he drank was 125 + 250 = 375 grams. So he consumed 375 * 2 = 750 grams of caffeine for the day. The answer is 750.
