the owner od the theater in item 18 wants to make at least $400 at each performance. let x be the number of adult tickets and y be the number of child tickets sold. white an inequality to show the number of tickets that need to be sold

The inequality representation is : x + y ≥ $400

Step-by-step 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
