Suppose you invested $1600 in the stock market 2 years ago. During the first year, the value of the stock increased by 13%. During the second year, the value of the stock decreased by 13%. How much money is your investment worth at the end of the two-year period? Did you earn money or lose money? (Note: The answer to this question is not $1600.)
 

We first get the value of the investment after 1 year. To get a 13% increase we multiply the investment of $1600 by *blank*  .

Increase = 1600    times(x)   *blank*  = $ *blank*

Nope....it is correct given the info in the Q

   1600 * 1.13 * .87 = $1572.96   at the end of two years (13% up the first year then down 13% the 2nd)
