The cost of a pottery painting party is $9 per person, plus a one-time supply fee of $89. which of the following functions model c(x), the average cost per person for the party? c(x)=9x+89x c(x)=9x+89x c(x)=9+899x c(x)=9x+899x

We have been given that the the cost of a pottery painting party is $9 per person, plus a one-time supply fee of $89.

As we can see from the conditions, as the number of persons increases, so does the cost. Also, we can see that the one-time supply fee is a constant and is independent of the number of people in the pottery painting party.

Now, since, the "person cost" of the part is $9 per person, let us assume that there are x people attending the party, then the total person cost will be $ 9x. Since $ 89 is the fixed cost, that will not change.

Thus, the function, c(x) that best models the he average cost per person for the party is:
