Suppose that you invest $7000 in a risky investment. At the end of the first year, the investment has decreased by 70% of its original value. At the end of the second year, the investment increases by 80% of the value it had at the end of the first year. Your investment consultant tells you that there must have been a 10% overall increase of the original $7000 investment. Is this an accurate statement? If not, what is your actual percent gain or loss on the original $7000 investment. Round to the nearest percent.
