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 cavities, what will the cost of the visit be?
Write your answer as an expression.

50+100x=?

Step-by-step explanation:

50 is the amount of money it is for a visit and the x represents how many cavities are being filled and the 100 is for how much it is per cavity to be filled.  For example if you needed 3 cavities filled then it would be 50+(100x3).

(Btw sorry if the equation for the step-by-step explanation is incorrect)

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
