Gloop Co. has a piece of equipment that it is considering selling. The net book value of the machine is $13,500. It can sell the equipment for $14,500. It will not incur any additional costs to sell the equipment. Another company has offered to lease the equipment for $5,000 per year for three years. If Gloop Co. leases the equipment, it would pay insurance, repair and maintenance costs of $300 per year over the term of the lease. Compute the differential income (loss) that will result if Gloop Co. chooses to lease the equipment rather than sell it. (Enter a loss as a negative number).
