Marin Inc is negotiating to lease a piece of equipment to Cullumber Inc. Cullumber requests that the lease be for 9 years. The equipment has a useful life of 10 years. Marin wants a guarantee that the residual value of the equipment at the end of the lease is at $6000. Cullumber agree to guarantee a residual value of this amount thought it expects the residual value of the equipment to be only 2500 at the end of the lease term. If the value of the equipment at lease commencement is 105,000 what would be the amount of the annual rental payments Marin demands of Cullumber, assuming each payment will be made at the beginning of each year and Marin wishes to earn a rate of return on the lease of 10%
