3. Saving for College. You want to create a college fund for a child who is now 3 years old. The fund should grow to $30,000 in 15 years. If an investment available to you will yield 6 percent per year, how much must you invest in a lump sum now to realize the $30,000 when needed? (Hint: Use Appendix A.2 or visit the Garman/

Forgue companion website.)
