conversations.value: This math problem has got me stumped: 3 people run for president.  John manages to capture 150 votes. James captures 70% of the remaining vote.  If there were 1150 people voting, how many more votes did the third guy get than John?
  Can you show me the way?

conversations.value: There were 1150-150=1000 people who didn't vote for John
  That means James got 1000*.7=700 votes
  So the other candidate got 1000-700=300 votes
  This means he got 300-150=150 more votes than John.
