Step-by-step reasoning process: At the beginning, Jacob had 8 fish. Alex had 7 * 8 = 56 fish. After knocking the bucket over, Alex was left with 56 - 23 = 33 fish left. The final amount caught by Jacob to beat Alex by 1 fish is 33 + 1 = 34 fish. Then Jacob needs to catch 34 - 8 = 26 fish more.
[Q & A] The question is At a recent fishing tournament, Alex caught 7 times as many fish as Jacob. Jacob did not think that he had any chance of winning, but Alex became overconfident and knocked over his bucket of fish, losing 23 fish back to the lake. If Jacob had 8 fish at the beginning, how many more fish does he need to catch to beat Alex by just 1 fish?
The answer is 26

Step-by-step reasoning process: If one intersection has 4 crosswalks, with 20 lines per crosswalk, there are 20 * 4 = 80 lines in all the crosswalks per intersection. If there are 5 intersections, the total number of lines in all the intersections is 80 * 5 = 400 lines.
[Q & A] The question is While driving up a road, Philip passed through 5 intersections. 4 crosswalks marked each intersection with a total of 20 lines per crosswalk. Calculate the total number of lines of the crosswalks in the five intersections.
The answer is 400

Step-by-step reasoning process: I would currently be 4 * 4 = 16 years old, since I'm 4 times older than Billy's age of 4. Therefore, in order to find my age at Billy's birth we'd simply subtract Billy's age of 4 from my age, meaning I was 16 - 4 = 12 years old.
[Q & A] The question is If I'm 4 times older than Billy currently, and Billy is 4 years old, how old was I when Billy was born?
The answer is 12

Step-by-step reasoning process: Hillary sells 3 crafts for 12 dollars each, for a total of 3 crafts * $12 / craft = $36. She receives an extra 7 dollars from a customer, increasing the total to $36 + $7 = $43. She then deposits 18 dollars in the bank, leaving her with $43 - $18 = $25.
[Q & A]
The question is At a flea market, Hillary sells handmade crafts for 12 dollars per craft. Today, Hillary sells 3 crafts and is given an extra 7 dollars from an appreciative customer. Later on, Hillary deposits 18 dollars from today's profits into her bank account. How many dollars is Hillary left with after making the deposit?
The answer is 25
