Bill buys a stock that decreases by 20% on the first day, and then on the second day the stock increases by 30% of its value at the end of the first day. What was the overall percent increase in Bill's stock over the two days?

x = stock price at purchase

      down 20 %    means 80% left     .8x    after 20% loss

          then up 30%          (1.3)(.8x) = final value    =1.04 x      final value is UP 4%
