Problema Solution
A man bought a car for $600 and sold it for $800. then he bought the car back for $1000 and then sold it for $1200. Then how much is his profit?
Answer provided by our tutors
He bought the car for $600: profit is -$600
Sold it for $800: profit is -$600 + $800 = $200
Bought it back for $1000: profit is $200 - $1000 = -$800
Sold it for $1200: profit is -$800 + $1200 = $400
Therefore, his profit is $400.
