[Question]The basketball team sold 50 cupcakes for $2 each and 40 cookies for $0.5 each. Then the money from their sales was used to buy two basketballs that cost $40 each. The rest of the money was used to buy 20 bottles of energy drinks. How much does a bottle of energy drink cost?
[Answer]The basketball team earned 50 x $2 = $100 from selling cupcakes. They also earned 40 x 0.5 = $20 from selling cookies. So their total earnings was $100 + $20 = $120. The two basketballs cost $40 x 2 = $80. Thus, $120 - $80 = $40 was used to buy the 20 bottles of energy drinks. Therefore, each bottle of energy drink costs $40 / 20 = $2. The answer is 2.
Q: In 5 years, Raven will be 4 times as old as Phoebe. If Phoebe is currently 10 years old, how old is Raven?
A: In five years, Phoebe will be 10 + 5 = 15 years old. If Raven is four times as old as Phoebe in fifteen years, he will be 4 * 15 = 60 years old in 5 years. Currently, Raven is 60 - 5 = 55 years old. The answer is 55.
Question: Silvia wants to buy a new guitar online. The price of the guitar has a suggested retail price of $1000. Guitar Center has a special deal of 15% off but has a shipping fee of $100. Sweetwater has a 10% off deal with free shipping. How much will she save by buying from the cheaper store compared to the other store?
Answer: The discount saved when buying from Guitar Center would be $1000 * 15% = $150. The total cost when buying from Guitar Center would be $1000 - $150 discount + $100 shipping = $950. The discount when buying from Sweetwater would be $1000 * 10% = $100. The total cost when buying from Sweetwater would be $1000 - $100 discount + $0 shipping = $900. Thus, Silvia would save $950 - $900 = $50 when buying from Sweetwater. The answer is 50.

Question: A spaceship is traveling to another planet. The spaceship travels at a consistent speed its entire journey unless it is stopped for the crew's break. After launch, the spaceship traveled for 10 hours then stopped for 3 hours. It then traveled for another 10 hours then stopped for 1 hour. After this, the spaceship would take an hour's break after every 11 hours of traveling and maintained this routine until the end of its journey. If the entire journey took 3 days then how long, in hours, was the spaceship not moving?
Answer:
On the first day, the spaceship spent a total of 10 hours + 10 hours = 20 hours traveling. On the first day, the spaceship spent a total of 3 hours + 1 hour = 4 hours not moving. This is a total of 20 hours traveling + 4 hours not moving = 24 hours or 1 day. So the rest of the journey took place over 3 days journey 1 first day = 2 days. This is the same as 2 days * 24 hours = 48 hours. In these 2 days, the spaceship's time is split into 11 hours traveling + 1 hour break = 12 hour blocks. So in the last 2 days, the spaceship wasn't moving for a total of 48 hours / 12 hour blocks = 4 hours. Adding this to breaks from the first day shows that the spaceship was not moving for a total of 4 + 4 = 8 hours. The answer is 8.
