Donald'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 = 65 + 145x[/tex]
B. [tex]C = 0.65 + 145x[/tex]
C. [tex]C = 65x + 145[/tex]
D. [tex]C = 0.65x + 145[/tex]

Answer :

To solve this problem, we need to create an equation that models the total amount of reimbursement the company offers based on the number of miles driven, represented by [tex]\( x \)[/tex].

Here's how to approach it:

1. Understand the Components:
- The company reimburses at a rate of \[tex]$0.65 per mile.
- Additionally, there is an annual maintenance reimbursement of \$[/tex]145.

2. Construct the Equation:
- Per Mile Reimbursement: If [tex]\( x \)[/tex] is the number of miles driven, then the reimbursement for mileage is [tex]\( 0.65 \times x \)[/tex].
- Annual Maintenance: Regardless of the miles driven, there is a fixed reimbursement of \$145 for maintenance.

3. Combine Components:
- The total reimbursement [tex]\( C \)[/tex] is the sum of the per mile reimbursement and the fixed annual maintenance amount.
- Therefore, the equation is:
[tex]\[ C = 0.65x + 145 \][/tex]

4. Match with Options:
- Look at the options provided:

A. [tex]\( C = 65 + 145x \)[/tex]

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

C. [tex]\( C = 65x + 145 \)[/tex]

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

- The correct equation is option D: [tex]\( C = 0.65x + 145 \)[/tex].

Therefore, the equation that correctly models the total reimbursement Donald's company offers, based on the number of miles driven, is given by option D.
