conversations.value: The price of Parmesan cheese is $11 per pound. Mozzarella cheese is $6 per pound.  Amor buys 2 pounds of Parmesan and 3 pounds of mozzarella cheese.  Is she starts with $50 cash, how much money, in dollars, will she have left to buy meat?
  Can you solve this problem?

conversations.value: The cost for buying 2 pounds of parmesan cheese is $11 x 2 = $22.
  The cost for buying 3 pounds of mozzarella cheese is $6 x 3 = $18.
  The total amount spent for the 2 kinds of cheese is $22 + $18 = $40.
  So, Amor still has $50 - $40 = $10 left to buy for meat.
