To figure out how much each company charges per mile, you need to calculate the additional cost per mile by subtracting the initial fee and dividing it by the number of miles.
For Company 1:
To find the additional cost per mile, you can subtract the initial fee from the rental charge and divide it by the number of miles. Let's take the first example:
Rental Charge: $53.55
Initial Fee: (unknown)
Let's assume the initial fee is x. So, we have:
$53.55 - x = additional cost per mile
For the first scenario, where the distance is 30 miles:
Additional Cost per mile = x / 30
You can repeat the same process for the remaining distances and calculate the additional cost per mile using the given rental charges for Company 1.
For Company 2:
Follow the same steps to calculate the additional cost per mile for Company 2:
Let's assume the initial fee is y. So, we have:
Rental Charge: $56.75
Initial Fee: (unknown)
$56.75 - y = additional cost per mile
Again, you can repeat the process for the remaining distances and calculate the additional cost per mile for Company 2 using the given rental charges.
Remember, you cannot directly divide the rental charge by the number of miles to calculate the cost per mile since it includes the initial fee as well.
