Question

price of a visit to the dentist is $50 if the dentist fills any cavities and additional charge of $100 for cavity gets added to the bill if it doesn't find any cavities what was the cause of the visit me​

Answer 1

The visit will cost you $50

Explanation:

Set up an equation:

Variable x = number of cavities

Variable y = cost of visit

y = 50 + 100x

If you had no cavities then x will equal 0

y = 50 + 100(0)

Anything multiplied by 0 is 0

y = 50 + 0

y = 50
