Final answer:
The total cost of leasing a vehicle for three years, including the security deposit, lease payments, and excess mileage charge, is $14,160.
Step-by-step explanation:
To calculate the total cost of leasing the vehicle for three years, we need to consider the security deposit, monthly lease payments, and any excess mileage charges.
The security deposit is $300, which is not earning any interest in a money market account. The monthly lease payments are $385 for a total of 36 months (3 years), resulting in $13,860 ($385 * 36).
Since the lease has a mileage restriction of 10,000 miles per year and it was exceeded by 8,000 miles over three years, there is a charge of 10 cents per excess mile. The excess mileage charge is therefore $800 (8,000 miles * $0.10).
The total cost of leasing the vehicle for three years is the sum of the security deposit, lease payments, and excess mileage charge, which amounts to $14,160 ($300 + $13,860 + $800).
