Question

A car rental company's standard charge includes an initial fee plus an additional fee for each mile driven.

Answer 1

Given:

S = 0.40M + 15.75

I = 0.15 M + 3.70

Let's find the equation for total charge C.

Let's write an equation relating C to M.

To write the equation, we have:

$C=S+I$

Now, add both equations:

$\begin{gathered} C=(0.40M)+15.75)+(0.15M+3.70) \\ \\ \text{ Remove parentheses and combine like terms:} \\ C=0.40M+0.15M+15.75+3.70 \\ \\ C=0.55M+19.45 \end{gathered}$

Therefore, the equation relating C to M is:

C = 0.55M + 19.45

ANSWER:

C = 0.55M + 19.45
