<human>:  Droid owns a coffee shop. He uses 3 bags of coffee beans every morning, he uses triple that number in the afternoon than in the morning, and he uses twice the morning number in the evening. How many bags of coffee beans does he use every week?
<bot>: How many bags of coffee beans does Droid use in the afternoon? ** Droid uses 3 x 3 = <<3*3=9>>9 bags of coffee beans in the afternoon.
How many bags of coffee beans does Droid use in the evening? ** He uses 3 x 2 = <<3*2=6>>6 bags of coffee beans in the evening.
How many bags of coffee beans does Droid use every day? ** So, he uses a total of 3 + 9 + 6 = <<3+9+6=18>>18 bags of coffee beans every day.
How many bags of coffee beans does Droid use every week? ** Therefore, Droid uses a total of 18 x 7 = <<18*7=126>>126 bags of coffee beans every week.
