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

Answer 1

The expression is-

50+100×v

Answer 2

The formula for a linear model is y=mx+b

The y represents the output value,

the m represents the rate of change,

the x represents the input value, and

the b represents the constant.

We will find that the cost of the visit is related with the linear equation:

C(n) = $100*n + $50

Here, we need to find an equation that gives the cost of the visit to the dentist.

We know that there is a fixed cost of $50, plus $100 for each cavity filled.

So, if the dentist fills 'n' cavities,

the cost will be the fixed $50 plus n times $100, this is:

C(n) = $50 + $100*n

This is the linear equation that models the cost of the visit.
