Answer:
Explanation:
Lets say Ali started out with $35
After she paid for the painting, she had $0 left.
Then she gained $55 from Aakash.
Then she bought the painting for $60, so now she has $-5.
(I know this makes no sense but it works.)
She sold it again for $80, so now she has $75.
75-35=40.
In the end, she gained $40.
Hope this helps!
