Linda is 10 years old. Her parents want to save for 4 years of college, starting at 18. Her parents want to deposit $X today and on birthdays 11, 12, … 17. On birthdays 18, 19, 20, 21, they plan to take out $20,000—the cost of college. How much do her parents need to save each year? Assume the discount rate is 10%.
