[Question]Carson is going to spend 4 hours at a carnival. The wait for the roller coaster is 30 minutes, the wait for the tilt-a-whirl is 60 minutes, and the wait for the giant slide is 15 minutes. If Carson rides the roller coaster 4 times and the tilt-a-whirl once, how many times can he ride the giant slide? (Wait times include the time actually spent on the ride.)
[Answer]First figure out how many minutes Carson spends at the carnival by multiplying the number of hours he's there by the number of minutes per hour: 4 hours * 60 minutes / hour = 240 minutes. Then figure out how long Carson spends waiting for the roller coaster by multiplying the wait time per ride by the number of rides: 4 rides * 30 minutes / ride = 120 minutes. Now subtract the time Carson spends on the roller coaster and tilt - a - whirl from the total time he spends at the park to find out how much time he has left: 240 minutes - 120 minutes - 60 minutes = 60 minutes. Now divide the time Carson has left by the wait time for the giant slide to see how many times he can ride it: 60 minutes / 15 minutes / ride = 4 rides. The answer is 4.
Q: Mary goes with her 3 children to the circus. Tickets cost $2 for adults and $1 for children. Mary pays with a $20 bill. How much change will she receive?
A: Mary's ticket costs $2 / ticket * 1 ticket = $2. Mary's children's tickets cost 3 tickets * $1 = $3. Together the tickets cost $2 + $3 = $5. After paying with a 20 - dollar bill, Mary will receive $20 - $5 = $15. The answer is 15.
Question: Ashley and her family went to the movies on Saturday. Children's tickets cost $4.25 and adult tickets cost $3.25 more. They were given a $2 discount for buying more than 3 tickets. How much did they spend if they bought two adult tickets and four children's tickets?
Answer: The adult tickets cost $4.25 + $3.25 = $7.50. So two adult tickets cost $7.50 x 2 = $15. Four children's tickets cost $4.25 x 4 = $17. So the total cost of all the tickets amounted to $15 + $17 = $32. The family had a discount, so they paid a total of $32 - $2 = $30. The answer is 30.
[Question]Kathleen receives a weekly allowance for completing all of her chores. During middle school, her allowance was $2 more than $8 but during her senior year, her allowance was $5 more than twice her middle school allowance. What is the percentage increase in Kathleen's weekly allowance?
[Answer]Kathleen's allowance in middle school was $8 + $2 = $10. Twice her middle school allowance is $10 x 2 = $20. So, Kathleen's senior year allowance is $20 + $5 = $25. Her allowance increased by $25 - $10 = $15. Kathleen's percent increase in her weekly allowance is $15 / $10 x 100% = 150%. The answer is 150.
Q: Henri has 8 hours to watch movies and read. He watches one movie that is 3.5 hours and one movie that is 1.5 hours. He then decides to read. If he can read 10 words a minute, how many words does he read before his free time is up?
A: He has 3 hours to read because 8 - 3.5 - 1.5 = 3. He has 180 minutes to read because 3 x 60 = 180. He can read 1,800 words because 180 x 10 = 1,800. The answer is 1800.
Question: Krystian works in the library. He borrows an average of 40 books every day. Every Friday, his number of borrowed books is about 40% higher than the daily average. How many books does he borrow in a week if the library is open from Monday to Friday?
Answer:
The number of books borrowed on Friday is higher by 40 * 40 / 100 = 16 books. There are 5 days from Monday to Friday inclusive, so Krystian borrows an average of 5 * 40 = 200 books during that time. With Friday's increase in borrowings, during one week Krystian borrows 200 + 16 = 216 books. The answer is 216.
