1 answer

To find out which car rental company is less expensive for a 300-mile trip, we need to calculate the total cost \(C\) for each company based on the given formulas.

For Top-Notch Car Rental:

  • Fixed cost: $150
  • Variable cost per mile: $0.35
  • Total miles: 300

The total cost for Top-Notch Car Rental can be calculated as follows: \[ C = 150 + 0.35m \] Substituting \(m = 300\): \[ C = 150 + 0.35 \times 300 \] \[ C = 150 + 105 \] \[ C = 255 \]

For Fleetwood Car Rental:

  • Fixed cost: $200
  • Variable cost per mile: $0.10
  • Total miles: 300

The total cost for Fleetwood Car Rental is calculated as follows: \[ C = 200 + 0.10m \] Substituting \(m = 300\): \[ C = 200 + 0.10 \times 300 \] \[ C = 200 + 30 \] \[ C = 230 \]

Comparison:

  • Total cost for Top-Notch Car Rental: $255
  • Total cost for Fleetwood Car Rental: $230

Now to determine which company is less expensive and by how much: Fleetwood Car Rental is less expensive.

To find the difference in cost: \[ \text{Difference} = 255 - 230 = 25 \]

Final Answer: The less expensive company is 2 by $25.
