Question

Administrators at a university will charge students $158 to attend a seminar. It costs $2160 to reserve a room, hire an instructor, and bring in the equipment. Assume it costs $50 per student for the administrators to provide the course materials. How many students would have to register for the seminar for the university to break even?

Answer 1

The cost per student is $50 so $108 is profit for the school
158-50=$108 profit
2160/50=43.2
43.2×50=2160
You need 44 students to break even

Answer 2

$158s = Cost per student

$50s + $2160 = Cost of Uni

158s = 50s + 2160

-50s -50s

108s = 2160

s = 20

At 20 students the university would break even.
