Give the step-by-step reasoning process and then the final answer. Nancy wants to figure out if she can afford to apply to the University of Michigan. The tuition costs $22,000 per semester. Her parents can pay half the cost, and each semester Nancy can get a scholarship for $3,000 and a student loan for twice her scholarship amount. If Nancy can work a total of 200 hours during the semester, how many dollars does she have to make per hour to pay the rest of the tuition?
First figure out how much Nancy has to pay after her parents pay their half by dividing the tuition by 2: $22,000 / 2 = $11,000. Then figure out how much Nancy's student loan is by multiplying her scholarship amount by 2: $3,000 * 2 = $6,000. Now subtract the amounts of Nancy's scholarship and loan to find out how much tuition she has to pay by working: $11,000 - $3,000 - $6,000 = $2,000. Now divide the remaining unpaid tuition by the number of hours Nancy works to find out how much she needs to make per hour: $2,000 / 200 hours = $10 / hour.
The final answer: 10.
