conversations.value: Can you break down the solution for me for this math problem: Mitzi brought $75 to the amusement park. She spent $30 on a ticket, $13 on food, and $23 on a T-shirt. How much money does she have left?

conversations.value: Mitzi spent a total of $30 + $13 + $23 = $66.
  So she still has $75 - $66 = $9 left.
