<human>:  During a fundraiser, each of the 20 members of a group sold candy bars which costs $0.50 each. If each member sold an average of 8 candy bars, how much money did they earn from their candy bars sales, in dollars?
<bot>: How many candy bars did the group sell? ** The group was able to sell 20 x 8 = <<20*8=160>>160 candy bars.
How much money did they earn from their candy bars sales? ** So, they got 160 x $0.5 = $<<160*0.5=80>>80 from their candy bars sales.
