conversations.value: Rose bought five dozens of eggs for $2.40 x 5 = $12.
  Five dozens of eggs is equal to 12 x 5 = 60 eggs.
  So there are 60/3 = 20 sets of 3 eggs that Rose will sell.
  Thus, the total earnings of Rose for selling the eggs are $1 x 20 = $20.
  Therefore, her profit will be $20 - $12 = $8.
