Answer:
$500 gain
Explanation:
Sonu spent $2500 on the fridge itself, and he also spent an additional $300 on the repairs. He spent a total of $2800. He sold the fridge for $3300.
To find the loss or gain, we can subtract 2800 from 3300 to see how much total profit he made.
3300-2800=500
Sonu made a $500 gain.
