Calculating stock return

I know the basic stock return calculation but I was wondering how I would calculate a short position divided in 1/2 and then taken in 1/3.

The short entry would be 150@235.29 and short 100@233.18 Then profit taking would be 100@230.77, 50@228.7199, 100@ 231.2092

What is the total return to the investor?

nm figured it out.
