75=100-100e%5E%28-0.01x%29
100e%5E%28-0.01x%29=100-75
100e%5E%28-0.01x%29=25
e%5E%28-0.01x%29=25%2F100
e%5E%28-0.01x%29=0.25
-0.01x=ln%280.25%29
0.01x=-ln%280.25%29
x=-ln%280.25%29%2F0.01<-->x=-ln%281%2F4%29%2F0.01<-->x=ln%284%29%2F0.01<-->x=100ln%284%29
So highlight%28x=100ln%284%29%29 is an elegant way to write the exact result,
but x=-ln%280.25%29%2F0.01 would allow you to calculate an approximate result with a calculator.
