I have a problem with finding the right formula. Normally you can use f(x)=a*(1+b))^x (a = base value, b = percentage, like 0,25)to calculate the absolute number of sth.
But I have a formula to claculate the percentage depending of x, so its changing all the time (decreasing to nearly zero).
The formula above doesn't work anymore, but i haven´t found other.
Can you help me???
If you don't understand what i mean, ask....english is not my native language and its hard to ecpress sth in it
