The basses take 3 * 4 = 12 strings. He restrings 2 * 3 = 6 normal guitars. That takes 6 * 6 = 36 strings. He restrings 6 - 3 = 3 guitars with 8 strings. So that uses 3 * 8 = 24 strings. So he uses 12 + 36 + 24 = 72 strings.
The answer: 72
Reverse engineering the question: John has to restring 3 basses with 4 strings each, twice as many guitars which have 6 strings each, and 3 fewer 8 string guitars than the normal guitars. How many strings does he need?
Reasoning and answer: James has 5000 - 276 = 4724 pennies. They donated a total of 5000 + 4724 = 9724 pennies.
The answer: 9724

Question: Cassandra collected 5000 pennies for the charity drive. James collected 276 fewer pennies. How many pennies did they donate to charity?
Andrew has 6 * 3 = 18 shirts. So, Steven has 4 * 18 = 72 shirts.
The answer: 72
Reverse engineering the question: Steven has 4 times as many shirts as Andrew. Andrew has 6 times as many shirts as Brian. If Brian has 3 shirts, how many does Steven have?
Reasoning and answer: She eats 3 beignets every morning and there are 7 days in a week so she eats 3 * 7 = 21 beignets in a week. She eats 21 beignets in a week so over 16 weeks she will have eaten 21 * 16 = 336 beignets.
The answer: 336

Question: Sandra eats 3 beignets every morning. How many beignets will she eat in 16 weeks?
After painting the red and blue pebbles, Shawn had a remainder of 40 - 9 - 13 = 18 pebbles. He painted 18 / 3 = 6 pebbles yellow. The difference between the number of blue and yellow pebbles is 13 - 6 = 7.
The answer: 7
Reverse engineering the question: Shawn collected 40 plain pebbles. He painted 9 pebbles red and 13 pebbles blue. He then divided the remaining pebbles equally into 3 groups, and painted them purple, yellow, and green. What is the difference between the number of blue and yellow pebbles?
In two years, Lennon will be 2 + 8 = 10 years old. Ophelia will be 4 * 10 = 40 years old in two years. Currently, Ophelia is 40 - 2 = 38 years old.
The answer: 38
Reverse engineering the question:
In two years, Ophelia will be four times as old as Lennon. If Lennon is currently eight years old, how old is Ophelia?
