Final answer:
Camille has budgeted $240 for her trip. By dividing this amount by the total distance of 53 miles, we can determine the cost per mile for her trip. Since Camille will drive 26.5 miles to her grandmother's house and then back to the airport, she will drive a total distance of 53 miles.

To calculate the total cost of the trip, we need to consider the cost of renting the car and the total distance driven. Since Camille will drive 26.5 miles to her grandmother's house and then back to the airport, she will drive a total distance of 53 miles. Now, we can calculate the cost per mile by dividing the total budget of $240 by the total distance of 53 miles. The cost per mile is $240 / 53 = $4.53 (rounded to two decimal places).
