Question: There were 600 people in the stadium when the football game started. Before the game was over, one-fourth of the boys and one-eighth of the girls left early. How many people remained to see the end of the game if there were 240 girls at the beginning of the game?
Answer: There were 600 - 240 = 360 boys at the beginning of the game. So, 360 x 1 / 4 = 90 boys left early. And 240 x 1 / 8 = 30 girls left early. A total of 90 + 30 = 120 people left early. Therefore, 600 - 120 = 480 people remained to see the end of the game. The answer is 480.
[Question]Tom decides to lease a car. He drives 50 miles on Monday, Wednesday, and Friday, and Sunday for the rest of the days he drives 100 miles. He has to pay $.1 per mile he drives. He also has to pay a weekly fee of $100. How much does he have to pay in a year.
[Answer]He does the long drive 7 - 4 = 3 days a week. So he drives a total of 4 * 50 + 3 * 100 = 500 miles a week. That means the car cost 500 * .1 = $50 just for the mileage per week. So he pays 100 + 50 = $150 per week for the car. That means the total cost of the car is 150 * 52 = $7800 a year. The answer is 7800.

Question: Bella has two times as many marbles as frisbees. She also has 20 more frisbees than deck cards. If she buys 2/5 times more of each item, what would be the total number of the items she will have if she currently has 60 marbles?
Answer: When Bella buys 2 / 5 times more marbles, she'll have increased the number of marbles by 2 / 5 * 60 = 24. The total number of marbles she'll have is 60 + 24 = 84. If Bella currently has 60 marbles, and she has two times as many marbles as frisbees, she has 60 / 2 = 30 frisbees. If Bella buys 2 / 5 times more frisbees, she'll have 2 / 5 * 30 = 12 more frisbees. The total number of frisbees she'll have will increase to 30 + 12 = 42. Bella also has 20 more frisbees than deck cards, meaning she has 30 - 20 = 10 deck cards. If she buys 2 / 5 times more deck cards, she'll have 2 / 5 * 10 = 4 more deck cards. The total number of deck cards she'll have is 10 + 4 = 14. Together, Bella will have a total of 14 + 42 + 84 = 140 items. The answer is 140.
[Question]Once a week, it takes Kitty 5 minutes to pick up toys and straighten the living room. It takes another 20 minutes to vacuum the living room floor, seating and drapes.
