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]$C = 45x + 175$[/tex]

B. [tex]$C = 0.45x + 175$[/tex]

C. [tex]$C = 0.45 + 175$[/tex]

D. [tex]$C = 0.45 + 175x$[/tex]

Answer :

To find the equation that models the total amount of reimbursement, represented by [tex]\( C \)[/tex], we need to consider two parts of the reimbursement package provided by the company:

1. Mileage Reimbursement: The company reimburses [tex]$0.45 per mile. If \( x \) represents the number of miles, then the total reimbursement for mileage is \( 0.45x \).

2. Annual Maintenance Fee: The company provides an additional $[/tex]175 a year for maintenance, regardless of the number of miles driven.

Combining these two parts, the total reimbursement [tex]\( C \)[/tex] is the sum of the mileage reimbursement and the annual maintenance fee. Therefore, the equation that models [tex]\( C \)[/tex] is:

[tex]\[ C = 0.45x + 175 \][/tex]

This matches with option B:

[tex]\[ B. \, C = 0.45x + 175 \][/tex]

So, the correct answer is option B.
