Tim's company offers a reimbursement package of [tex]\$0.45[/tex] per mile plus [tex]\$175[/tex] a year for maintenance. If [tex]x[/tex] represents the number of miles, which equation below models [tex]C[/tex], the total amount of reimbursement the company offers?

A. [tex]C = 0.45x + 175[/tex]
B. [tex]C = 45x + 175[/tex]
C. [tex]C = 0.45 + 175x[/tex]
D. [tex]C = 0.45 + 175[/tex]

Answer :

To solve this problem, we need to find an equation that models the total amount of reimbursement, [tex]\( C \)[/tex], that Tim's company offers. The reimbursement is based on two components:

1. A variable component of [tex]\(\$0.45\)[/tex] per mile.
2. A fixed annual maintenance reimbursement of [tex]\(\$175\)[/tex].

We can represent the total reimbursement [tex]\( C \)[/tex] with the number of miles [tex]\( x \)[/tex].

Here's how we set up the equation:

1. Variable Reimbursement: Since the company reimburses [tex]\(\$0.45\)[/tex] for each mile, the total reimbursement for mileage can be expressed as [tex]\( 0.45 \times x \)[/tex], where [tex]\( x \)[/tex] is the number of miles.

2. Fixed Reimbursement: The company also provides a fixed reimbursement of [tex]\(\$175\)[/tex] for maintenance for the entire year. This value stays constant regardless of the miles driven.

3. Total Reimbursement Equation: To find the total reimbursement, we add the variable reimbursement to the fixed annual maintenance. Therefore, the equation is:
[tex]\[
C = 0.45x + 175
\][/tex]

Now, let's compare this with the provided options. The correct equation is:

A. [tex]\( C = 0.45x + 175 \)[/tex]

This equation matches the model we developed based on the reimbursement package provided by Tim's company.
