Susan is beginning to plan college savings accounts for her two children. Her son Bobby is 8 and will begin college in 10 years when he turns 18.
Her daughter Mallory is 2 and will begin college in 16 years when she is 18. Susan plans to deposit $10,000 per year starting next year into a joint account that earns 8.0% annually. Her last deposit will occur in the year that Bobby starts school.
If Bobby's schooling costs $25,000 each year for four years, and Mallory's schooling costs $30,000 each year for four years, will Susan's plan provide enough money for both her children's college education?
By how much will Susan meet/miss the goal when she quits depositing money in year 10?
(Assume schooling costs are paid after the year is completed, i.e. Bobby's first tuition payment will occur at end of year 11)
