<human>:  Paul is collecting license plates from different states. He has plates from 40 different states. For each percentage point of total US states that he has, his parents will give him $2. How much does he earn from them?
<bot>: How many plates does Paul have out of total states? ** The proportion of plates that he has out of total states is .8 because 40 / 50 = <<40/50=.8>>.8
How many plates does Paul have out of total states? ** He has 80% of the plates because .8 x 100 = <<.8*100=80>>80
How much does Paul earn from his parents? ** He makes $160 because 80 x 2 = <<80*2=160>>160
