  Randy has $200 in his piggy bank. He spends 2 dollars every time he goes to the store. He makes 4 trips to the store every month. How much money, in dollars, will be in his piggy bank after a year?

conversations.value: Randy spends 2*4=8 dollars every month.
  Randy spends 8*12=96 dollars in a year.
  Randy will have 200-96=104 dollars in his piggy bank after a year.
