The cost per person if number of students is 100 given the inverse variation is $46.75
Inverse variation
- Cost per person = C
- Number of students = n
C = k / n
where,
k = constant of proportionality
If n = 55 and C = $85
C = k / n
85 = k / 55
85 × 55 = k
4,675 = k
Find C if n = 100
C = k / n
= 4,675 / 100
C = $46.75
