Hi,
I'm coding a PHP/MySQL application.
I'm looking for the formula to compute the original variable after it
has been applied VAT.
For instance 100 + 18% -> 118.
But if I try to find out 100 from 118 - 18%, the result is greater than
100.
I don't have enough maths background to solve the equation:
c = a + (a*b/100)
I'm stuck at this point:
a = (a*b/100) -c
I would like to have all 'a' on the left side and b and c on the right.
Can someone help?
