Question: Brian goes fishing twice as often as Chris, but catches 2/5 times fewer fish than Chris per trip. If Brian caught 400 fish every time he went fishing, how many fish did they catch altogether if Chris went fishing 10 times?
Answer: Step-by-step reasoning process: If Brian caught 400 fish in one trip, he caught 2 * 400 = 800 fish in two trips. Since Brian catches 2 / 5 times less fish than Chris per trip, Chris catches 2 / 5 * 400 = 160 more fish in one fishing trip. Chris's total number of fish in one trip is 400 + 160 = 560 fish. In 10 trips, Chris catches 560 * 10 = 5600 fish. If in his two trips Brian catches 800 fish, and he goes fishing twice as often as Chris, if Chris goes fishing 10 times, Brian will catch 800 * 10 = 8000 fish. The total number of fish they'll catch if Chris goes fishing ten times is 8000 + 5600 = 13600.
So the answer is 13600.

Question: The chances of making the junior high basketball team start at 10% if you're 66 inches and increase 10% for every additional inch of height. Devin starts out as 65 inches tall, then grows 3 inches. What are his chances of making the basketball team?
Answer: Step-by-step reasoning process: First find Devin's new height by adding his growth to the original height: 65 inches + 3 inches = 68 inches. Then subtract 66 inches from Devin's height to find how many extra inches of height he has: 68 inches - 66 inches = 2 inches. Then multiply the number of extra inches by the percentage increase per inch to find the total percentage increase in his chances: 2 inches * 10% / inch = 20%. Then add the percentage increase to the base percentage to find Devin's overall chance of making the basketball team: 10% + 20% = 30%.
So the answer is 30.

Question: Between them, Mark and Sarah have 24 traffic tickets. Mark has twice as many parking tickets as Sarah, and they each have an equal number of speeding tickets. If Sarah has 6 speeding tickets, how many parking tickets does Mark have?
Answer: Step-by-step reasoning process: First figure out how many total speeding tickets the two people got by adding the 6 speeding tickets Sarah got to the equal number (6) that Mark got: 6 + 6 = 12. Now subtract the combined number of speeding tickets from the total number of tickets to find the combined number of parking tickets: 24 - 12 = 12. Now express Mark's number of parking tickets in terms of the number of parking tickets Sarah got: m = 2s. We know that m + s = 12, so substitute in the value of m from the previous step to get 2s + s = 12. Combine like terms to get 3s = 12. Divide both sides of the equation to get s = 4. Now multiply the number of parking tickets Sarah got by 2 to find the number Mark got: 4 * 2 = 8.
So the answer is 8.

Question: A library has a collection of 100 historical novels arranged on a shelf. 5 people borrow 2 books each from the shelf on a particular day, and 20 more books are borrowed from the shelf on the second day. How many books are remaining on the shelf after the second day?
Answer:
Step-by-step reasoning process: Five people borrowed 5 people * 2 books / person = 10 books on the first day. After the second day, the total number of borrowed books increased to 10 books + 20 books = 30 books. The total number of books on the shelf after the second day is 100 books - 30 books = 70 books.
So the answer is 70.
