<human>:  Sammy can eat 15 pickle slices. His twin sister Tammy can eat twice as much as Sammy. Their older brother Ron eats 20% fewer pickles slices than Tammy. How many pickle slices does Ron eat?
<bot>: How many pickle slices does Tammy eat? ** Tammy can eat twice as many pickle slices as Sammy who eats 15 so Tammy can eat 15*2 = <<15*2=30>>30 pickle slices
How many pickle slices does Ron eat? ** Ron eats 20% fewer pickle slices than Tammy who eats 30 pickle slices so that's .20*30 = <<20*.01*30=6>>6 fewer slices than Tammy
How many pickle slices does Ron eat? ** Tammy eats 30 slices and Ron eats 6 less, then Ron eats 30-6 = <<30-6=24>>24 pickle slices
