Here is the equation which I end up to while solving a problem in my Traffic and Transportation Engineering book.
I will appreciate if you can show me the steps. On my own, I tried taking the ln on both side of the equation in order to get raid of e, but I am not getting right result. In fact I am doubting if my approach makes sense.
My initial approach:
this will eliminate e, and than I solve. but yet I am not getting the right answer.. I doubt this approach makes sense.. so if you have a way out. please show your work.
