Border Patrol Practice Exam 2025 – Comprehensive Preparation Resource

To find out how many miles the officer drove, we first need to determine the total cost of the rental and how that cost breaks down.

The officer rented the car for six days at a daily rate of $35. The total cost for the rental days alone can be calculated as follows:

Daily charge = $35

Number of days = 6

Total daily charges = $35 * 6 = $210

Next, to find the total amount that went towards mileage, we subtract the daily charges from the total amount paid:

Total amount paid = $450

Total daily charges = $210

Total charge for mileage = Total amount paid - Total daily charges = $450 - $210 = $240

The rental company also charges $0.30 per mile. To find out how many miles were driven, we use the cost allotted to mileage and divide it by the per-mile charge:

Cost per mile = $0.30

Total charge for mileage = $240

Miles driven = Total charge for mileage ÷ Cost per mile = $240 ÷ $0.30 = 800 miles

This shows that the officer drove a total of 800 miles during the rental period, confirming that this is the correct calculation for the question
