conversations.value: Break down this math problem: John throws a block party and splits the cost with 3 other people.  They buy 100 pounds of burgers at $3 per pound.  They also buy $80 of condiments and propane to cook everything.  John also buys all the alcohol which costs $200. How much did John spend altogether

conversations.value: He splits the cost 3+1=4 ways
  100 pounds of burgers at $3 per pound makes 100*3=$300
  In addition to $80 for condiments and propane the total cost was 300+80=$380
  That means each of them paid 380/4=$95
  Then adding in the cost of alcohol, John spent 200+95=$295
