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 = 0.65x + 145[/tex]

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

D. [tex]C = 65x + 145[/tex]

Answer :

Sure! To find the equation that models the total reimbursement, we need to understand both components of the reimbursement package:

1. Reimbursement per mile: Donald's company offers [tex]$0.65 per mile. If he drives \( x \) miles, the reimbursement from driving would be \( 0.65 \times x \).

2. Annual maintenance cost: The company also provides a fixed maintenance reimbursement amount of $[/tex]145 per year, regardless of how many miles are driven.

We want to find an equation, [tex]\( C \)[/tex], that gives us the total reimbursement Donald's company offers based on the number of miles [tex]\( x \)[/tex]. This can be expressed as:

[tex]\[ C = \text{(reimbursement per mile)} \times x + \text{(annual maintenance cost)} \][/tex]

Substituting in the given numbers:

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

This equation means that for every mile driven, [tex]$0.65 is added up, and a constant $[/tex]145 is added once to account for annual maintenance.

Therefore, the correct equation is found in option B: [tex]\( C = 0.65x + 145 \)[/tex].
