Q: Kingsley's teacher instructed her to find four friends to help her carry some chairs to the school hall to be used for an upcoming event. If each student carried 5 chairs per trip and made 10 trips in total, what's the total number of chairs taken to the hall?
A: Kingsley and her four friends sum up to 4 + 1 = 5 students carrying chairs. The number of chairs carried by each student after all the trips is 10 * 5 = 50. Since each student carried 50 chairs, the total number in the hall is 50 * 5 = 250. The answer is 250.

Q: In the Golden State Team, each player earned points. Draymond earned 12 points, Curry earned twice the points as Draymond, Kelly earned 9, Durant earned twice the points as Kelly, Klay earned half the points as Draymond. How many points did the Golden States have in total?
A: Curry earned 12 x 2 = 24 points. Durant earned 9 x 2 = 18 points. Klay earned 12 / 2 = 6 points. Therefore, Golden States has a total of 12 + 24 + 9 + 18 + 6 = 69 points. The answer is 69.

Q: The school is hosting a race after school. The winner is the person who runs the most laps around the school in 12 minutes. One lap around the school is 100 meters. The winner is awarded a gift certificate equal to $3.5 for every one hundred meters they run. The winner runs 24 laps around the school. On average, how much did they earn per minute?
A:
They ran 2,400 meters because 24 laps x 100 m / lap = 2400 m. They ran 200 meters per minute because 2400 m / 12 min = 200 m / min. For every minute they ran they earned an average of $7 because $3.5 / 100m x 200 m / min = $7 / min. The answer is 7.
