Video Planet (VP) sells a big screen TV package consisting of a 60-inch plasma TV, a universal remote, and on-site installation by VP staff. The installation includes programming the remote to have the TV interface with other parts of the customers home entertainment system. VP concludes that the TV, remote, and installation service are separate performance obligations. VP sells the 60-inch TV separately for $1,500 and sells the remote separately for $120, and offers the entire package for $1,600. VP does not sell the installation service separately. VP estimates that it incurs approximately $120 of compensation and other costs for VP staff to provide the installation service. VP typically charges 50% above cost on similar sales. Assuming using the expected cost plus margin approach to estimate stand-alone selling price, how much of the transaction price would be allocated to the installation service?
