Suppose that you have $9,000 in a rather risky investment recommended by your financial advisor. during the first year, your investment decreases by 70% of its original value. during the second year, your investment at the end of year one increases by 80%. your advisor tells you that there must have been a 10% overall increase of your original $9,000 investment. is your financial advisor using percentages properly? if not, what is your actual percent gain or loss of your original $9,000 investment?
