Q: Tom decided to go on a trip. During this trip, he needs to cross a lake, which in one direction takes 4 hours. During this time, Tom needs an assistant to help him with the crossing. Hiring an assistant costs $10 per hour. How much would Tom have to pay for help with crossing the lake back and forth?

Question: Gerald spends $100 a month on baseball supplies. His season is 4 months long. He wants to use the months he's not playing baseball to save up by raking, shoveling, and mowing lawns. He charges $10 for each. How many chores does he need to average a month to save up for his supplies?
Answer: He needs to save up $400 because 4 x 100 = 400. He has 8 months to earn this money because 12 - 4 = 8. He needs to earn $50 a month because 400 / 8 = 50. He needs to do 5 tasks a month because 50 / 10 = 5. The answer is 5.

Q: Will and Henry go fishing in a river. Will catches 16 catfish and 10 eels. Henry challenges himself to catch 3 trout for every catfish Will catches. Due to environmental concerns, Henry decides to return half his catch after meeting his own challenge. How many fishes do they have altogether now?
A: Will caught 16 + 10 = 26 fishes. Henry caught 3 trout for each catfish Will caught so since Will caught 16 catfish, Henry caught 16 * 3 = 48 trout. Half of 48 trout is (1 / 2) * 48 = 24. Henry returned 24 trout leaving him with 48 - 24 = 24 trout. They now have a total of 26 + 24 = 50 fishes. The answer is 50.
Question: Mrs. Wilsborough saved $500 to buy concert tickets for her family. She bought 2 VIP tickets at $100 each and 3 regular tickets at $50 each. How much of her savings does Mrs. Wilsborough have after she buys the tickets?
Answer:
The 2 VIP tickets amount to $100 x 2 = $200. The 3 regular tickets amount to $50 x 3 = $150. Thus, the total cost of the tickets is $200 + $150 = $350. Therefore, Mrs. Wilsborough is left with $500 - $350 = $150 of her savings. The answer is 150.
