Answer: the man made $200
Step-by-step explanation:
The price at which the man bought the laptop is $500.
The price at which the man sold the laptop is $600.
Profit or loss is expressed as selling price - cost price. Therefore, the profit made is
600 - 500 = $100
The man buys laptop again for $700. The price at which the man sold the laptop is $800. The profit made is
800 - 700 = $100
Total amount of profit made is 100 + 100 = $200
