[Question]Christopher, Jameson, and June each bought a toy sword. June's sword is 5 inches longer than Jameson's sword. Jameson's sword is 3 inches longer than twice the length of Christopher's sword. Christopher's sword is 15 inches long. How many inches longer is June's sword than Christopher's sword?
[Answer]Twice the length of Christopher's sword is 15 x 2 = 30 inches. So, Jameson's sword is 30 + 3 = 33 inches long. June's sword is 33 + 5 = 38 inches long. Thus, June's sword is 38 - 15 = 23 inches longer than Christopher's sword. The answer is 23.

[Question]Alicia has 20 gumballs. Pedro has that many gumballs plus an additional number of gumballs equal to three times the number Alicia has. They put their gumballs in a bowl, and later Pedro takes out 40% of the gumballs to eat. How many gumballs are remaining in the bowl?
[Answer]If Pedro has three times more gumballs than Alicia, he has 3 * 20 gumballs = 60 gumballs more. In total, Pedro has 20 gumballs + 60 gumballs = 80 gumballs. When they put their gumballs together, the total number of gumballs in the bowl becomes 20 gumballs + 80 gumballs = 100 gumballs. Pedro takes out 40% of the gumballs which is 40 / 100 * 100 gumballs = 40 gumballs. The number of gumballs remaining is 100 gumballs - 40 gumballs = 60 gumballs. The answer is 60.

[Question]At the end of the first quarter, the winning team had double the points of the losing team. At the end of the second quarter, the winning team had 10 more points than it started with. At the end of the third quarter, the winning team had 20 more points than the number it had in the second quarter. If the total points the winning team scored in the game was 80, and the losing team had 10 points in the first quarter, calculate the total number of points the team scored in the fourth quarter.
[Answer]At the end of the first quarter, the winning team had double the points of the losing team, meaning the winning team had already scored 10 * 2 = 20 points. At the end of the second quarter, the winning team had 10 more points than it started with, a total of 20 + 10 = 30 points. At the end of the third quarter, the winning team had 20 more points than the number it had in the second quarter, a total of 20 + 30 = 50 points. If the total points the winning team scored in the game was 80, they scored 80 - 50 = 30 points in the fourth quarter. The answer is 30.

[Question]Mark and his sister Chris both leave their house for school at the same time. Mark travels at the same speed as Chris, who walks 3 miles per hour. After walking 3 miles Mark has to turn around and go home because he forgot his lunch. If the distance from their house to the school is 9 miles, how much longer does Mark spend walking than Chris?
[Answer]
First find the total number of miles Mark walks to get his lunch by multiplying the distance he walks back to the house by 2: 3 miles * 2 = 6 miles. Then find the total distance Mark walks by adding that distance to the distance between the house and the school: 6 miles + 9 miles = 15 miles. Now divide the total distance Mark walks by his speed to find how many hours he spends walking: 15 miles / 3 miles / hour = 5 hours. Now divide the total distance Chris walks by her speed to find the total time she spends walking: 9 miles / 3 miles / hour = 3 hours. Now subtract the time Chris spends walking from the time Mark spends walking to find the difference: 5 hours - 3 hours = 2. The answer is 2.
