Answer: The required inequality will be 50+x>$300
Explanation:
Since we have given that
Amount raised for charity = $10
Amount raised on Saturday = $50
Amount raised on both Saturday and Sunday is more than $300.
Let the amount raised on Sunday be 'x'.
So, Inequality becomes,
Saturday + Sunday > $300
50+x>$300
x>$300-$50
x>$250
So, On Sunday he must raised more than $250.
Hence, the required inequality will be
50+x>$300
