A local high school requires at least one adult chaperone for every 12 students on any field trip. The principal uses the inequality y = x/12 to verify that this rule is met. The ordered pair (50, 5) is in the solution set of the inequality. What does (50, 5) represent?

a.5 adult chaperones and 50 students going on the field trip
b.5 students and 50 adult chaperones going on the field trip
c.50 people going on the field trip, 5 of whom are adult chaperones
d.50 people going on the field trip, 5 of whom are students

Question

A local high school requires at least one adult chaperone for every 12 students on any field trip. The principal uses the inequality y >= x/12 to verify that this rule is met. The ordered pair (50, 5) is in the solution set of the inequality. What does (50, 5) represent?

a.5 adult chaperones and 50 students going on the field trip
b.5 students and 50 adult chaperones going on the field trip
c.50 people going on the field trip, 5 of whom are adult chaperones
d.50 people going on the field trip, 5 of whom are students

Mercury · Answer

one variable represents the # of students and the other represents the # of chaperones (eliminating c and d)

now, considering the problem, and the way the inequality is set up, then between 5 and 50, which number do you think is the number of students, and which is the number of chaperones?
