conversations.value: Troy makes soup.  He buys 4 pounds of beef and 6 pounds of vegetables.  The vegetables cost $2 per pound and the beef is 3 times that price.  How much does everything cost?
  Can you solve this problem?

conversations.value: The vegetables cost 2*6=$12
  The beef cost 2*3=$6 per pound
  So the beef cost 4*6=$24
  So the total cost is 12+24=$36
