A local high school requires at least one adult chaperone for every 12 students on any field trip. The principal uses the inequality y is greater than or equal to x over 12 to verify that this rule is met. The ordered pair open paren 50 comma 5 close paren is in the solution set of the inequality. What does open paren 50 comma 5 close paren represent?

In the inequality y ≥ x/12, x represents the number of students and y represents the number of adult chaperones. The ordered pair (50, 5) means 50 students and 5 adult chaperones. Since 50/12 is about 4.17, at least 5 chaperones are required, so this pair meets the rule. The correct choice is 5 adult chaperones and 50 students going on the field trip.
