Tirn's company offers a reimbursement package of [tex]$\$0.65$[/tex] per mile plus [tex]$\$145$[/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 = 65x + 145[/tex]
B. [tex]C = 65 + 145x[/tex]
C. [tex]C = 0.65 + 145x[/tex]
D. [tex]C = 0.65x + 145[/tex]

Answer :

To figure out which equation represents the total amount of reimbursement, [tex]\( C \)[/tex], the company offers, let's break it down into parts:

1. Per Mile Reimbursement: The company offers [tex]$0.65 per mile. If \( x \) is the number of miles driven, then the cost for the mileage is \( 0.65 \times x \).

2. Fixed Yearly Maintenance Reimbursement: Besides the mileage reimbursement, there's a fixed amount of $[/tex]145 that the company compensates for maintenance annually. This amount is constant and does not depend on the number of miles driven.

Now, combining these two components, the total reimbursement [tex]\( C \)[/tex] is calculated as:

[tex]\[ C = \text{(Mileage Reimbursement)} + \text{(Fixed Maintenance Cost)} \][/tex]

Substituting the values we know:

[tex]\[ C = 0.65x + 145 \][/tex]

So, the equation that models the total reimbursement [tex]\( C \)[/tex] the company offers is:

D. [tex]\( C = 0.65x + 145 \)[/tex]

This equation accurately represents both the variable cost based on mileage and the fixed annual cost for maintenance.
