We will find that the cost of the visit is modeled with the linear equation:

c(n) = $100*n + $50.

How to write a model equation?

Here we need to find an equation that models the cost of the visit to the dentist.

We know that there is a fixed cost of $50, plus $100 for each cavity filled.

So, if the dentist fills n cavities, the cost will be the fixed $50 plus n times $100, this is:

C(n) = $50 + $100*n

This is the linear equation that models the cost of the visit.
