Final answer:
The total cost to use the car for one day and travel 250 km is $129.95. This is calculated by first determining the fixed daily charge from the given information and then adding the cost per kilometer for the additional distance.
Step-by-step explanation:
To calculate the cost to use the car for one day and travel 250 km, we first need to determine the fixed daily charge and the variable cost per kilometer. From the given information, we know that the total cost for one day and traveling 200 km is $107.45, and the variable cost per kilometer is $0.45/km.
First, let's calculate the total variable cost for 200 km: 200 km × $0.45/km = $90. Then, we subtract this amount from the total cost to find the fixed daily charge: $107.45 - $90 = $17.45. Now that we have the fixed daily charge, we can calculate the cost for traveling 250 km: Fixed daily charge + (250 km × $0.45/km) = $17.45 + ($112.50) = $129.95.
Hence, the total cost to use the car for one day and travel 250 km would be $129.95.
