Consider the Q and A. Q: Matt has 8 baseball cards worth $6 each. If he trades two of them to Jane in exchange for 3 $2 cards and 1 $9 card, how much profit does he make?
A: 3
What is the step-by-step reasoning process?
Step-by-step reasoning process: First find the value of the 2 cards Matt trades: $6 / card * 2 cards = $12. Then find the total value of the 3 $2 cards: 3 cards * $2 / card = $6. Then subtract the value of the cards Marcus gave up from the value of the cards he gained to find his profit: $9 + $6 - $12 = $3.

Consider the Q and A. Q: Polly the parakeet tweets all day long. When she is happy, she tweets 18 times per minute. When she is hungry, she tweets 4 times per minute. And when she watches herself in the mirror, she tweets 45 times per minute. During a time period where she is happy for 20 minutes, hungry for 20 minutes, and watches her reflection for 20 minutes, what is the total number of times she will tweet?
A: 1340
What is the step-by-step reasoning process?
Step-by-step reasoning process: In 20 minutes, she happy tweets for 20 * 18 = 360 times. In 20 minutes, she hungry - tweets for 20 * 4 = 80 times. In 20 minutes, she tweets at her reflection 20 * 45 = 900 times. Altogether, she tweets 360 + 80 + 900 = 1340 times.

Consider the Q and A. Q: Elsa and her sister watch an opera show every year at Central City Opera. Last year, opera seating cost $85 per ticket. This year, it costs $102. What is the percent increase in the cost of each ticket?
A: 20
What is the step-by-step reasoning process?
Step-by-step reasoning process: The ticket price increase is $102 - $85 = $17. So there is 17 / 85 x 100% = 20% increase of price.

Consider the Q and A. Q: Ayla has a customer care job whose primary role is to hear complaints from customers and advise them on the best way to solve their problems. She talks with each customer for a limited amount of time, and each phone call is charged five cents per minute. If each call lasts 1 hour, what's the phone bill at the end of the month if she manages to talk to 50 customers a week?
A: 600
What is the step-by-step reasoning process?
Step-by-step reasoning process:
An hour has 60 minutes. If each call lasts an hour, the total amount of money charged is 60 * .05 = $3 for 1 customer. When she talks to 50 clients in a week, the total amount of money charged is 50 * 3 = $150. In a month of 4 weeks, the phone bill is 150 * 4 = $600.
