Some friends of yours have just had a child. Thinking ahead, and realizing the power of compound interest, they are considering investing for their child’s college education, which will begin in 18 years. Assume that the cost of a college education today is $125,000. Also assume there is no inflation and no tax on interest income used to pay college tuition and expenses.
