For this case, the first thing we should do is define a variable.

  • x: percentage of plant growth

The formula that models this problem is given by:


x = \frac  initial\ height-final\ height  {initial\ height} * 100

Substituting values we have:


x = \frac  6-12  {6} * 100

Rewriting:


x = \frac  -6  {6} * 100\\x = \frac {6} {6} * 100\\x = 100\%

Answer:

The percent increase in the height of the plants is 100%
