A car rental company charges a daily fee, plus an additional fee for each mile driven. Susan rented a car for one day, drove 100 miles, and was charged $48.00. Bob rented a car for one day, drove 224 miles, and was charged $72.80. How much does the company charge for a one-day rental and 172 miles driven?

A. $56.60
B. $60.40
C. $62.40
D. $68.00

C. $62.40

Step-by-step explanation: After hours of trying, I finally figured it out. We have to find out what the fee is for each mile...

224 - 100 = 124

$72.80 - $48 = $24.8

124 miles = $24.8

$24.8 divided by 124 = $0.2

Now, we know each mile is worth $0.2. Let's multiply 172 and the value of each mile...

$0.2 x 172 = $34.4

Now, let's try to find the daily fee...

100 miles = 100 x 0.2 = $20

$48 - $20 = $28

The daily fee is worth $28...now let's put everything together.

$28 + $34.4 = $62.40

I hope this helps!

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
