[Question]The Diving Club offers 2 beginning diving classes on weekdays and 4 beginning classes on each day of the weekend. Each class has room for 5 people. How many people can take classes in 3 weeks?
[Answer]There are 2 classes x 5 days = 10 classes on weekdays. There are 4 classes x 2 days = 8 classes on weekends. There are a total of 10 + 8 = 18 classes per week. So each week, 18 x 5 = 90 people can take classes. Thus, 90 x 3 = 270 people can take classes in 3 weeks. The answer is 270.

[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.

[Question]Caleb is baking a birthday cake for his grandfather. His grandfather is turning 79 years old. Caleb puts three colors of candles on the cake. He puts one candle for each year for his grandfather. He puts 27 yellow candles, 14 red candles and the rest are blue candles. How many blue candles did he use?
[Answer]Caleb has put 27 + 14 = 41 yellow and red candles. So, he used 79 - 41 = 38 blue candles. The answer is 38.
