If Faith attends college, it will take her four years, during which time she will earn no income. She will pay $50,000 for tuition, $12,000 for room and board, and $5,000 for books. If she spends the four years working rather than attending college, she will pay $18,000 for room and board, pay no intuition, and buy no books. Based on this information, Faith's economic cost of attending college would be $67,000 if, over the four years, she could earn

$18,000 instead of attending college.
