Answer :
I will do step by step:
A) First we have to find the total cost considering that it will take one week as the question says "You rent an 8-passenger van for a week". They will travel 2480 miles in total (round-trip). Thus:
"The rate is $399.00 a week with 1.500 free miles and 80.25 per additional mile." Mathematically this means:
[tex]\text{Total cost = 399 + 80.25}\times(2480-1500)[/tex]Obs: The additional miles are (2480-1500).
The CDW fee is $165.00 for the week, and the estimated gasoline cost is $600.00. It is one week, so we can add it into the total cost formula:
[tex]\text{Total cost = 399 + 80.25}\times(2480-1500)\text{ + 165 + 600}[/tex]Making the calculations, the total cost will be:
[tex]\text{Total cost = }79809\text{ dollars}[/tex]B) The full course is 2480 miles, so to find the round-trip per mile we can divide them:
[tex]\text{Total cost per mile = }\frac{79809}{2480}\approx32.2\text{ }[/tex]C) Per person is the same reasoning:
[tex]\text{Total cost per person = }\frac{79809}{8}=9976.125[/tex]
