No, no no.  If you have some number, 376.7, and we say it is the result
of a 25% loss, the equation is:

.75x = 376.7

therefore, x = 502.3.

When you decrease something by 25%, you cannot get back to the original
by increasing the new value by 125%.  Percentages, not scalars.
Remember the old addage, if you lose 50% of your money, you need a 100%
profit return to get back to the beginning. Damn percentages... :)
