Chris is planning for her son's college education to begin five years from today. She estimates the yearly tuition, books, and living expenses to be $5,000 per year for a four-year degree. How much must Chris deposit today, at an interest rate of 8 percent, for her son to be able to withdraw $5,000 per year for four years of college?
S = P (1 %)^n, 20000 = P 1.08^5, P = 20000/1.08^5 = 13620. That's why the correct answer is B: 13620
