The percentage in increase can be calculated as follows:
% of increase = (difference between new and old amounts / old value) *100
For Dario:
difference in values = 413 - 350 = 63
% of increase = (63/350)*100 = 18%
For Monica:
difference in values = 270 - 225 = 45
% of increase = 20%
Therefore,
Monica has higher percent of increase.
The difference in percents = 20% - 18% = 2%
There are 20 gallons of 20% butterbeer solution.
Assume there are x gallons of 80% solution.
So total amount of the solution will be (x+20) gallons
The final solution is 50%.
So, we can set up the equation as:

.
Thus, there will be 20 gallons of 80% butterbeer solution that is needed to be mixed with 20 gallons of 20% butterbeer solution.
