[Question]Phil likes to collect baseball cards. He buys a pack of twenty each week for a year, but then loses half of them one day in a fire. How many baseball cards does Phil have left?
[Answer]Since there are 20 cards in a pack and 52 weeks in a year, Phil starts by collecting 20 * 52 = 1040 baseball cards. He then loses half of them for 1040 / 2 = 520 cards remaining. The answer is 520.

Question: John used to go to the gym multiple times a weak but because of lockdowns he hasn't been able to go. He used to lift 700 for squat, 400 for bench, and 800 for deadlift. For squat he lost 30% of his lift. He didn't lose any weight on bench because he was able to train that at home and he lost 200 pounds on deadlift. What is his new total?
Answer: He lost 700 * .3 = 210 pounds on squat. So his squat is now 700 - 210 = 490 pounds. His deadlift is 800 - 200 = 600 pounds. So his total is now 490 + 600 + 400 = 1490 pounds. The answer is 1490.
[Question]Mary bought 5 boxes of drinks at $6 each box and 10 boxes of pizzas at $14 each box for her pizza party. She paid $200 for all the items. How much change did she get back?
[Answer]Mary spent 5 x $6 = $30 on drinks. She spent 10 x $14 = $140 on pizzas. She spent a total amount of $30 + $140 = $170. Therefore, Mary got a change of $200 - $170 = $30 after paying all the items for her pizza party. The answer is 30.
Q: Anna has 3 times as many toys as Mandy and 2 fewer toys than Amanda. If they have 142 toys all together, how many toys does Mandy have?
A: Let x be the number of toys Mandy has. Anna has 3 * x toys. Amanda has 3 * x + 2 toys. x + 3 * x + 3 * x + 2 = 142. 7 * x + 2 = 142. 7 * x = 140. x = 20. The answer is 20.
Question: In a week, Rayman works out for half the number of hours Junior takes to work out. Wolverine, their friend, works out for twice the combined total number of hours both Rayman and Junior take during their workouts. Calculate the number of hours Wolverine takes doing her workouts if Rayman does workouts for 10 hours in a week.
Answer:
If Rayman takes 10 hours doing his workouts, half the number of hours junior takes, then Junior takes 2 * 10 = 20 hours to do his workouts in a week. Altogether, Junior and Rayman take 20 + 10 = 30 hours doing their workouts in a week. Wolverine takes 2 * 30 = 60 hours to do her workouts in a week, twice the total number of hours Rayman and Junior takes. The answer is 60.
