What was the question for this implicit rationale, and corresponding answer?
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.
 The answer: 340
