comment Algebra equation for percentage increase needed to get the current value as a 20% discount
thanks for writing this all out, it was easy to follow. Also completely different from Jonas approach, but with the same answer. Reviewing his equation, his is the same as yours except = 1 and not 100.

Actually, I'm thinking of setting up my website so independent sales people can sell my products, and their customers enter a code that gives them a 20% discount but then I also know who's code it is and they get their commission. So, their customers get the actual price and someone that doesn't use the sales code gets jacked (the 25% increase we figured out below), aka I'm not undercutting the sales people.

@Tony Yes, I'm aware this was an algebra question and not a calculus one. As it being linear algebra, I couldn't remember if it was.

@Jonas ty again, I worked through it on my own and came up with the same. These exchanges are great! If you ever have C#/asp.net coding questions head over to stackoverflow.com and I'd be happy to answer them!

@Jones ty for dumbing it down, @Tony no I don't have kids. I'm not dumb, just haven't thought in equations for a long time. I've forgotten all my calculus. I probably couldn't do an integral to save my life now.

Yes - thank you. How do you write those equations... I came up for X = ((1/(1-20/100)-1)*100) and my math is so rusty, I don't know what to do with that right side to reduce it.

I'm reading over it trying to figure it out. How come it isn't A^2 in the first equation, since you had an A for both the plus and the minus?
