<human>:  A bicycle store is running a promotion. Every time a customer buys a bicycle, they will receive 2 bike clamps free with it. If the store sells 19 bikes in the morning and 27 bikes in the afternoon, how many bike clamps has the store given to customers?
<bot>: How many bike clamps does the store give away in the morning? ** In the morning, the store gives away 19 bikes * 2 bike clamps = <<19*2=38>>38 bike clamps.
How many bike clamps does the store give away in the afternoon? ** In the afternoon, they give away 27 bikes * 2 bike clamps = <<27*2=54>>54 bike clamps.
How many bike clamps has the store given to customers? ** So in total, the store has given away 38 + 54 = <<38+54=92>>92 bike clamps.
