  Give me a solution to this problem

conversations.value: Tammy can eat twice as many pickle slices as Sammy who eats 15 so Tammy can eat 15*2 = 30 pickle slices
  Ron eats 20% fewer pickle slices than Tammy who eats 30 pickle slices so that's .20*30 = 6 fewer slices than Tammy
  Tammy eats 30 slices and Ron eats 6 less, then Ron eats 30-6 = 24 pickle slices
