Answer:

The cost of the visit to the dentist is:

  • $250.

Step-by-step explanation:

When using the formula provided in the exercise:

  • Dentist visit cost = 50 + 100n

Where n is the number of cavities found, you simply must replace the number provided by the exercise, instead of the letter n, since it is mentioned that 2 cavities were found, it is replaced as shown below:

  • Dentist visit cost = 50 + 100 (2)

So first you multiply and then add:

  • Dentist visit cost = 50 + 200
  • Dentist visit cost = 250

Therefore, the cost of the visit is $250.
