Answer this question:The stadium seats 60,000 fans, but only 75% of the seats were sold for the music show. Because of the threat of rain, 5,000 fans stayed home. How many attended the show?
The number of seats sold was 0.75 * 60,000 = 45,000. And 45,000 - 5,000 = 40,000.
The answer is 40000.

Answer this question:James and John combine their friends lists. James has 75 friends. John has 3 times as many friends as James. They share 25 friends. How many people are on the combined list?
John has 75 * 3 = 225 people on his friends list. So that means there are 225 + 75 = 300 people on the list. So once you remove duplicates there are 300 - 25 = 275 people.
The answer is 275.

Answer this question:Cindy had 20 marbles which is 5 more than what Lisa had. If Cindy gave her 12 marbles, how many more marbles does Lisa have now?
Lisa had 20 - 5 = 15 marbles. Since Cindy gave 12 marbles, then she only has 20 - 12 = 8 marbles left. Since Lisa received 12 marbles, then Lisa has 15 + 12 = 27 marbles now. Hence, Lisa has 27 - 8 = 19 marbles more than Cindy.
The answer is 19.

Answer this question:An Italian restaurant earns $600 every weekday and twice as much on the weekend. How much money does it earn by the end of the month?
On weekdays it earns $600 / weekday * 5 weekdays = $3000. During the weekend it earns twice as much each day so it makes ($600 * 2) / weekend day * 2 weekend days = $2400. Every week it earns $3000 + $2400 = $5400. By the end of the month, it earns $5400 / week * 4 weeks = $21600.
The answer is 21600.
