conversations.value: Every day, Billie bakes 3 pumpkin pies for 11 days and puts them in the refrigerator.  It takes 2 cans of whipped cream to cover 1 pie.  If Tiffany comes over and eats 4 pies, how many cans of whipped cream does Billie need to buy to cover the remaining pies?
  Can you solve this problem?

conversations.value: In total Billie bakes 3 x 11 = 33 pies.
  After Tiffany eats the pies, this many pies are in the refrigerator: 33 - 4 = 29 pies.
  She needs to buy this many cans of whipped cream 29 x 2 = 58 cans.
