The equation to describe the pattern is as follows;

C(s) = s + 50

The cost for 40 and 50 students are $90 and $100 respectively

To determine whether a function is linear or nonlinear, see whether it has a constant rate of change.

Therefore,

student : 20 - 10 = 10, 30 - 20 = 10, 40 - 30 = 10

Cost: 70 -60 = 10, 80 - 70 = 10

Using linear equation,

y = mx + b

where

m = slope

b = y-intercept

m = 70 - 60 / 20 - 10 = 1

60 = 10(1) + b

b = 50

Therefore,

y = x + 50

C(s) = s + 50

where

s = number of student

C(s) = cost

C(40) = 40 + 50 = 90

C(50) = 50 + 50 = 100
