conversations.value: There are 15 scouts and Ron wants to make sure they each get 2 s'mores a piece, for a total of 15*2 = 30 s'mores
  1 chocolate bar can make 3 s'mores and he wants to have enough for 30 s'mores, so he needs 30/3 = 10 chocolate bars
  Each chocolate bar costs $1.50 and he needs 10, for a total of 1.5*10 = $15.00
