Answer:
Option C
Step-by-step explanation:
There are several types of costs in this problem:
* Unique costs
* Costs that depend on the number of cars
* Costs that depend on the number of months
* Costs that depend on the number of months and the number of cars.
The costs that depend on the number of cars represent the coefficient of the variable n.
The costs that do not depend on the number of cars represent the constant value of the equation.
Then, to solve this problem you must identify the costs that do not depend on the number of cars.
These costs are:
* Membership Fee: $ 50 (one-time cost)
* Pull Pressure Check Cost: $ 15 per month
[tex]\$50 + \$15(12\ month) = \$230[/tex]
Then the answer is option C
