The total cost of the monthly payments is $290.50 * 36 months = $10,478.
The total cost of the excess miles is $0.18/mile * 1,200 miles = $216.
The total cost of leasing is the sum of the down payment, the monthly payments, and the excess mileage charge: $1,500 + $10,478 + $216 = $11,194.
Therefore, Fred's total cost of leasing was $11,194.
