Hey there,
#1 step
So the first thing that we will do is do 12.50 × 380.5 because 12.50 is how much she owes per mile and 380.5 is the amount that Kate would drive. So we do 12.50 × 380.5 and that will give us your answer to be C.)
So now we know that Kate will have to spend 474.56 to the car rental company.

Hope this helps you.
