The relation is inverse, when n increases, c decreases:
c=k/n
where k is a constant
when n=3→c=$24→$24=k/3
Solving for k:
3($24)=k
$72=k
k=$72
c=k/n
c=72/n→nc=72
What function models the data?
nc=72
if n=12→c=$72/n=$72/12→c=$6
How much per person will it cost if 12 students go on the trip?
$6
Answer: First option: nc=72, $6
