c 1/p
c=30 when p=50
c = kp
30= k* 50
k=3/5
when p= 40
c= 3/5 * 40
c=24

I don't know what the other person did and I'm not about to determine it either.
Doesn't he/she realize that the problem mentions "varies inversely?" Does he/she even know what this means?
I can tell you this, what he/she did was WRONG. I'll let you know this: with the relationship being an INVERSE one, it would cost less people MORE
money each. So, if 50 go on the trip, and each pays $30, do you think if 40 go, the 40 would pay less, per person than the 50, or more? I leave this for you to ponder!!
