conversations.value: Benny is baking pies for a bake sale. He plans to make ten pumpkin pies, which cost $3 each to make, and twelve cherry pies, which cost $5 each to make. If he wants to make a profit of $20 selling all the pies, how much does he have to charge for each pie if both kinds sell at the same price?

conversations.value: Benny will spend 3 * 10 = $30 to make the pumpkin pies.
  He will spend 5 * 12 = $60 to make the cherry pies.
  He wants to make a profit of $20, so he has to earn 30 + 60 + 20 = $110 selling all the pies.
  He is making 22 pies, so he needs to charge 110 / 22 = $5 per pie.
