(3) ROI = 55 / 95 = 58%
(This calculation is correct because when you remove $5 from the investment, the profit goes up by $5)
You've accounted for that $5 profit twice here, by both adding it to your profits and removing it from your expenses. You're double dipping. Do one or the other, not both.
If you count rakeback as pure profit then simply add it to your returns, 55/100=55%.
Alternatively, you could argue that you never really invested that $5 in the first place, in which case you'd subtract it from the amount you invested. 50/95 = 52.6%.
