Question: A bag contains 50 fewer baseball cards than football cards. There are 4 times as many football cards as hockey cards. If there are 200 hockey cards in the bag, how many cards are there altogether?
Answer: If there are 200 hockey cards in the bag and 4 times as many football cards as hockey cards, there are 4 * 200 = 800 football cards. The total number of football and hockey cards in the bag is 800 + 200 = 1000 cards. The bag contains 50 fewer baseball cards than football cards, meaning there are 800 - 50 = 750 baseball cards. Altogether, there are 750 + 1000 = 1750 cards. The answer is 1750.
[Question]Aron spends 30 minutes/day three times a week vacuuming and 20 minutes/day 2 days a week dusting. How much time does he spend cleaning total each week?
[Answer]First find the total time Aron spends vacuuming: 30 minutes / day * 3 days / week = 90 minutes / week. Then find the total time Aron spends dusting: 20 minutes / day * 2 days / week = 40 minutes / week. Then add those two times to find Aron's total cleaning time per week: 90 minutes / week + 40 minutes / week = 130 minutes / week. The answer is 130.

[Question]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?
[Answer]
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.
