conversations.value: Can you guide me through solving this problem: Paul earns $12.50 for each hour that he works. He then has to pay 20% for taxes and fees. After working 40 hours, Paul receives his paycheck. If he spends 15% of his paycheck on gummy bears, how much, in dollars, does he have left?

conversations.value: His pay before taxes and fees is $12.50 x 40 hours = $500.
  He pays $500 * 0.20 = $100 for taxes and fees.
  Then he had $500 - $100 = $400 remaining money.
  He takes out $400 * 0.15 = $60 for his gummy bears.
  So he's left with $400 - $60 = $340.
