conversations.value: Mario needs to buy snowshoes for his 6 sled dogs.  Assuming his dogs each has four legs and each pair of snowshoes costs $12.00, how much will it cost him to buy snowshoes for all of his dogs?

conversations.value: Dogs have 4 legs and a pair is 2 legs so each dog has 4/2 = 2 pair of legs
  There are 6 dogs and they each have 2 pair of legs so they have 6*2 = 12 pair of legs
  The snowshoes cost $12 per pair and he needs to buy 12 pairs so he will spend 12*12 = $144 on snowshoes
