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.

Answer 1

Cost of visit = 50 + 100n

Explanation:

$50 is the set price of the visit.

$100 is the cost per cavity.

N is the number of cavities.

Since we don't know the number of cavities, 'n' will fill that spot.

100 x n will be the total cavity cost.

Cavity cost + set price of visit will equal the total cost of the visit.
