[Question]One ticket to the underground costs $3. In one minute, the metro sells an average of 5 such tickets. What will be the earnings from the tickets in 6 minutes?

Q: Lefty scores 20 points in a game and his teammate Righty scores half as many as Lefty does. Their other teammate scores 6 times as much as Righty does. What are the average points scored per player on the team?
A: First, we need to determine how many points Righty scored. To do this we perform 20 / 2 = 10 points since Righty scored half as many as Lefty did. Then, to find the other teammate's points we perform 10 * 6 = 60 points scored, as they scored 6 times as many as Righty did. We then add all three teammates' points together, performing 20 + 10 + 60 = 90 points as the first step towards finding the average. We then divide this sum by the total number of players we're averaging, getting 90 / 3 = 30 points per player. The answer is 30.
Question: In a school, the number of participants in the 2018 Science Quiz Bowl was 150. There were 20 more than twice the number of participants in 2019 as there were in 2018. In 2020, the number of participants was 40 less than half the number of participants in 2019. How many more participants were there in 2019 than in 2020?
Answer: Twice the number of participants in 2018 is 150 participants x 2 = 300 participants. The number of participants in 2019 was 300 participants + 20 participants = 320 participants. Half the number of participants in 2019 is 320 participants / 2 = 160 participants. The number of participants in 2020 was 160 participants - 40 participants = 120 participants. There were 320 participants - 120 participants = 200 more participants in 2019 than in 2020. The answer is 200.
[Question]Rebecca drinks half a bottle of soda a day. She bought three 6-packs of sodas the last time she was at the store. How many bottles of soda will she have left after four weeks?
[Answer]Rebecca bought 3 * 6 = 18 bottles of soda. A week is 7 days, so she will drink 4 * 7 = 28 half bottles of soda in four weeks. A bottle is two half bottles, so she will drink 28 / 2 = 14 bottles of soda in four weeks. Thus, after 4 weeks, she will have 18 - 14 = 4 bottles of soda left. The answer is 4.
Q: Celia is creating a budget for the next 4 weeks. She wants to spend no more than $100 a week on food. For rent for her apartment, she plans to spend $1500. She has $30 set aside for video streaming services for the month. She also has $50 planned for one month of cell phone usage. After she adds up all of her spending for the month she wants to set aside 10% of it to put into savings. How much money is Celia going to put into her savings account?
A: Celia has budgeted $100 a week for 4 weeks for food, $100 x 4 = $400 worth of food for the month. She has one monthly cost of $1500 for her rent + $30 for video streaming services + $50 for her cell phone = $1580 of single monthly costs. Celia wants to set aside 10% of the $400 + $1580 = $1980 for her savings account. 10% of her savings account is .10 x 1980 = $198 to add to her savings account. The answer is 198.
Question: A chef has served 58 adults, 35 fewer children than the number of adults, and twice as many seniors as children. What is the total number of guests served?
Answer:
The chef has served 58 - 35 = 23 children. The chef has served 23 x 2 = 46 seniors. Therefore, the total number of guests that the chef has served is 58 + 23 + 46 = 127. The answer is 127.
