A young couple planning ahead for their retire­ment has decided that $3 million is the amount they will need in order to retire comfortably 20 years from now. For the past 5 years, they have been able to invest one of their salaries ($50,000 per year, which includes employer contributions) while living off the other salary. They plan to start a family sometime in the next 10 years and when they will have their first child, one of the parents will quit working, causing the savings to decrease to $10,000 per year thereafter. If they have realized an average ROR of 10% per year on their invest­ments, and expect to continue at this ROR, is reaching their goal of $3 million in 20 years sensi­tive to when they have their first child (i.e., be­tween now and 10 years from now)? If so, how

many years from now will they have to wait before they have their first child? Use a future worth analysis. What will be an ideal response?
