sure?

hartnn · Answer

yes.

lgbasallote · Answer

why not $1?

hartnn · Answer

because he profited $1 in BOTH transactions.

lgbasallote · Answer

if he bought for $7 then sold for $8 that means he got $1 profit. then, he bought for $9 that means he lost $1...so since it's increment-decrement..it becomes 0. then he sold for $10...doesn't that mean he gained $1?

hartnn · Answer

nopes.Lets say he had $100.bout for 7-->93$,sold for 8--->101$--->bought for 9--->92$--->sold for 10---->102$
net profit = 2$.
