conversations.value: Solve the math problem: A club opens up and charges $20 to enter.  James buys 2 rounds for his 5 friends.  He also buys 6 drinks for himself. Drinks cost $6 each.  He decides to eat some food so he orders some fried chicken which costs $14.  He leaves a 30% tip on everything he orders.  How much did he spend for the night?

conversations.value: He buys 2*5=10 drinks for his friends
  So he orders 10+6=16 total drinks.
  The cost of the drinks was 16*6=$96
  So his order came out to 96+14=$110
  The tip came out to 110*.3=$33
  So his order cost 110+33=$143
  Adding in the cover charge means it cost 143+20=$163
