Question

the price of a visit to the dentist is $50. if the dentist fills any cavities, an additional charge of $100 per cavity gets added to the bill. if the dentist finds n cavities, what will the cost of the visit be? write your answer as an expression.

Explanation:

Step1: Identify fixed and variable costs

The fixed cost for the visit is $50. The variable cost is $100 per cavity, and there are \( n \) cavities. So the variable cost is \( 100n \).

Step2: Combine fixed and variable costs

To find the total cost, we add the fixed cost and the variable cost. So the total cost \( C = 50 + 100n \).

Answer:

\( 50 + 100n \)
