Answer:

$C=0.65M+22.65$

Step-by-step explanation:

The standard charge includes an initial fee and plus an addditional fee for each mile driven and is given by:

$S=0.40M+17.75$

The insurance charge is given by:

$I=0.25M+4.90$

So, the total charge C will be the sum of the standard charge S and the insurance charge I:

$C=S+I$

Substitute:

$C=(0.40M+17.75)+(0.25M+4.90)$

Rearrange:

$C=(0.40M+0.25M)+(17.75+4.90)$

Add:

$C=0.65M+22.65$

And we have acauired our equation relating C to M!

Doris says 0 is not a rational number is she correct?

Sedaia [141]

As far as I know 0 IS a rational number. The only ones that are not rational are negative numbers. :) Though I could be wrong.....
