Lets give you a math lesson..
20% of 100 is 80.. So you got 20% less MPG then you currently get..
But, if you work the problem the other way. 125% of 80 is 100 mpg. Which is what really happened. So you have 25% better fuel efficiency.
This can be represented by the quation (x+1)(a+d) = a Where x is our percent increase (Or decrease), a is our gas mileage before, d is the difference in mileage before and after. This is the way you represent ammount changed from original, aka 25% more than base ammount.
You represented the problem with the equation (x+1)(c-d) = c Where x is our increase, c is our current gas mileage after the change, and d is the difference between current and past. This way, you represent the ammount you would have to flucuate from current to get the to past ammount. aka 20% less than current ammount.
