Answer:

  x = 9

Step-by-step explanation:

The first day, the value was multiplied by 1+30% = 1.30.

The second day, the value was multiplied by 1-30% = 0.70.

Over the 2-day period, the value was multiplied by 1+x%:

  1 -x/100 = (1.30)(0.70) = 0.91

  x/100 = 1 -0.91

  x = 9

The stock fell by 9% overall.
