PLEASE HELP DUE IN 5 MINS

A recent conference had 750 people in attendance. In one exhibit room of 70 people, there were 18 teachers and 52 principals. What prediction can you make about the number of principals in attendance at the conference?

There were about 193 principals in attendance.
There were about 260 principals in attendance.
There were about 557 principals in attendance.
There were about 680 principals in attendance.

Answer 1

To make a prediction about the number of principals in attendance at the conference, we can assume that the proportion of principals in the exhibit room is similar to the proportion of principals in the overall conference.

In the exhibit room, the proportion of principals is:

52/70 = 0.743

If we assume that this proportion is similar to the proportion of principals in the overall conference, we can estimate the number of principals in attendance at the conference as:

0.743 x 750 = 557.25

Therefore, we can predict that there were about 557 principals in attendance at the conference, which is closest to option C, 557 principals.

So the answer is C. There were about 557 principals in attendance.
