Samsung sells its four flagship productscell phones, TVs, computing devices, and memory storage devicesthrough its exclusive showroom in a city. To support sales, it has hired 20 per-sons and trained them to service every product. Depending on the nature of the job, the cost of overhead expenses varies.
