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?
Droid uses 3 x 3 = <<3*3=9>>9 bags of coffee beans in the afternoon.
He uses 3 x 2 = <<3*2=6>>6 bags of coffee beans in the evening.
So, he uses a total of 3 + 9 + 6 = <<3+9+6=18>>18 bags of coffee beans every day.
Therefore, Droid uses a total of 18 x 7 = <<18*7=126>>126 bags of coffee beans every week.
