Step-by-step reasoning process: Let the number of square feet in Benedict's house be x. So, we can write the equation 4 * x + 600 = 10000. Subtracting 600 from both sides we get 4 * x = 9400. Dividing both sides by 4 we get x = 2350 square feet.
The question and answer:
Question and answer: Kennedy's house is 600 square feet larger than 4 times Benedict's house. If Kennedy's house is 10000 square feet, how many square feet is Benedict's house?
The answer is 2350

Step-by-step reasoning process: 900 x 3 / 4 = 675 people came before the start of the concert. 900 - 675 = 225 people did not come before the start of the concert. 225 x 5 / 9 = 125 people came few minutes after the first song. So, 125 + 80 = 205 people came to the concert that was not able to be at the start of the concert. Therefore, 225 - 205 = 20 people did not go to the concert.
The question and answer:
