conversations.value: Can you break down the solution for me for this math problem: Sara got her first paycheck of two weeks of work. She had worked 40 hours a week at $11.50 per hour. The first thing she did was buy a new set of tires for her car for $410. How much money was she left with?

conversations.value: Sara worked 40 * 2 = 80 hours over two weeks.
  She earned 11.50 * 80 = $920
  After buying new tires, she had $920 - 410 = $510 left.
