My investment in Edgewater stocks is losing half its value every 2 years. Find and interpret the associated decay rate.
If I use the formula y=100(1/2)^x (< Is that correct?)
I got the answer of 0% (its wrong), I used a different formula, which should be wrong and got the answer of 25% and 34%
Is that the formula to solve the equation? Why is it wrong? How should I solve it?
Thank you
