but the transactions are independent of one another make 2 make 3 total 5 but on your side is none of us drunken idiots here the RR have come up with your answer so stick with itif i wasn't told this was commonly answered incorrectly, i probably would've gone with 5 just like the rest of the crew. knowing this was a teaser, i reworked the problem as such :
+2 off the first sale
rebuying at $9 erases the +2 profit and sets our boy back a cool $2 dollars. ok, so he's at -$2 prior to the 2nd sale. selling at a +3 profit on his second shot results in the following...
-2 + 3 = +1 profit
That's my answer and I like the fact that no one else has gone with it yet
