when I was considering what to do with my $10,000 lottery winnings, my broker suggested that I invest half of it in gold, the value of which was growing by 9% per year, and the other half and certificates of deposit (CDs), which were yielding 3% per year, compounded every six months. Assuming that these rates are sustained, how much will my investment be worth in 8 years?
