You want to lease a new car from a dealership. The value of the Car is $28,000 and the monthly lease payments will be $259/month for 36 months. There is $2,900 due at lease signing and the lease buyout value at the end of the 36 months is $17,400. There is a limit of 36,000 miles on the lease, but you estimate that you will actually drive it 45,000 miles. The penalty cost, at the end of the lease, for extra mileage is $0.20 per mile. What is the implied interest rate of the lease (including the extra mileage over the life of the lease)?

please use financial calculator on both way
