The initial cost of a pickup truck is $12,859 and will have a salvage value of $4,027 after 5 years. Maintenance is calculated to be a uniform gradient amount of $181 per year, with zero dollars for first year maintenance. The operation cost is calculated to be $0.27 per mile for 331 miles per month. If the interest rate is 12%, calculate the annual equivalent cost (AEC) for the truck?
