Question: A pelican caught 13 fish and a kingfisher caught 7 more fish than the pelican. If a fisherman caught 3 times the total amount of fish the pelican and kingfisher caught, how many more fish did the fisherman catch than the pelican?
Answer: The kingfisher caught 13 + 7 = 20 fish. The pelican and kingfisher caught 13 + 20 = 33 fish. The fisherman caught 3 x 33 = 99 fish. The fisherman caught 99 - 13 = 86 more fish than the pelican. The answer is 86.

Question: Bobby needed to make some trips with his truck and had only 12 gallons of gasoline. He drives to a supermarket 5 miles away and then drives back home. Then he headed to his farm which was 6 miles away. Two miles into the journey, he turned around and drove back home to retrieve some farming tools he forgot to take earlier and drove down to the farm. If he now has exactly 2 gallons of gasoline left, at what rate in miles per gallon has his truck been consuming gasoline?
Answer: The trip to the supermarket and back home covers 5 + 5 = 10 miles. The round trip of two miles each before he actually went to the farm covers 2 + 2 = 4 miles. Six miles to the farm and the total mileage is 10 + 4 + 6 = 20 miles. The truck consumed 12 - 2 = 10 gallons of gasoline for the total journey. So, the rate is 20 / 10 = 2 miles per gallon. The answer is 2.

Question: Sarah's age is equal to three times Mark's age minus 4. Mark is four years older than Billy. Billy is half Ana's age. If Ana will be 15 in 3 years, how old is Sarah?
Answer: First figure out how old Ana is right now by subtracting 3 from 15: 15 - 3 = 12. Next, figure out how old Billy is by dividing Ana's age by 2: 12 / 2 = 6. Now figure out how old Mark is by adding 4 to Billy's age: 6 + 4 = 10. Now, to figure out Sarah's age, first multiply Mark's age by 3: 10 * 3 = 30. Finally, subtract 4 from triple Mark's age to find Sarah's age: 30 - 4 = 26. The answer is 26.

Question: Billy's family likes to keep their bicycles stored in the garage when they're not being used. They own a total of 4 bicycles. Each bicycle wheel has 10 spokes. How many spokes are inside the garage?
Answer:
Each bicycle has 2 wheels, so there are a total of 4 * 2 = 8 wheels in the garage as there are 4 bicycles. Since each wheel has 10 spokes, this means there are 8 * 10 = 80 spokes in total. The answer is 80.
