Answer the following question.
Mr. Langsley commutes to work every day by bus. The bus picks him up at 6:00 a.m. and takes forty minutes to arrive at the first station. If Mr. Langsley arrives at work at 9:00 a.m., what's the total time taken in minutes from the first station to Mr. Langsley's workplace?
Step-by-step reasoning process: The total time taken for the whole journey is 9:00 - 6:00 = 3 hours. The total time taken in minutes is 3 * 60 = 180 minutes. If it takes 40 minutes to reach the first station, then the rest of the journey takes 180 - 40 = 140 minutes.
The answer is 140.

Answer the following question.
Tom eats a pound of carrots and twice as much broccoli. If carrots have 51 calories per pound and broccoli has 1/3 that many calories, how many calories did he eat in total?
Step-by-step reasoning process: He ate 2 * 1 = 2 pounds of broccoli. There are 51 / 3 = 17 calories in each pound of broccoli. So he ate 2 * 17 = 34 calories of broccoli. He ate 1 * 51 = 51 calories of carrots. So in total he ate 51 + 34 = 85 calories.
The answer is 85.

Answer the following question.
Percy wants to save up for a new PlayStation, which costs $500. He gets $200 on his birthday and $150 at Christmas. To make the rest of the money, he's going to sell his old PlayStation games for $7.5 each. How many games does he need to sell to reach his goal?
Step-by-step reasoning process: He needs to earn $150 more dollars because 500 - 200 - 150 = 150. He needs to sell 20 games because 150 / 7.5 = 20.
The answer is 20.
