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 dendist finds n cavities, what will the cost of the visit be?

Step-by-step explanation:

Hello! I hope you are having a nice day!

To solve this problem, we just need to create a formula for the scene.

We can start off by creating the formula. We know that the base for just visiting is 50 dollars. That means, for the start, we must always have 50 dollars for the base cost.

We also know that for every cavity the dentist finds/fixes, an additional 100 dollars is added in. We can represent sets of 100 by multiplying it by a number.

For example, if the dentist finds 5 cavities, it will cost 100(5)$ which is 500 dollars. We would then add 50 for the overall cost, being 550$.

To create a formula to do that, we can have 100n which n is the number of cavities.

Since we have the two parts, we can now create our full expression.

We will represent the total cost with . Whilst the others are self explanatory.

Again, we know that the starting cost for just looking at you is 50 dollars, and for every cavity found it costs 100 dollars to fix them.

Therefore, that would be our equation and our answer.

Have a nice day!

step-by-step explanation:

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
