The cost per student of a camping trip varies inversely as the number of students who attend. It will cost each
student $85 if 28 students attend. Approximately how
many students would have to attend to get the cost
down to $74.37?
A:32
B:2,380
C:36
D:40

16 is the coefficient

hope this

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
