Answer:
The inequality representation is : x + y ≥ $400
Explanation:
Inequality is the comparison and boundary for two non equal values. So inequality compares the non equal values.
As the owner wants to make $400 and sets boundary that;
Least amount to make = $400
Highest amount to make= infinite
This introduces relation in inequality as $400 or greater than $400.
The money made is counted combine from child tickets and adult tickets. If x is the made made through child tickets and y is from the adult then,
x + y ≥ $400
