The cost of a pottery painting party is $9 per person, plus a one time supply fee of $89. which of the following function model c(x), the average cost per person for the party?

For this case we first define the following variables:
 x = number of people
 We now write the function that models the problem:
 c (x) = (9x + 89) / x
 
 The average cost per person for the party is:
 c (x) = (9x + 89) / x
