Ozzy's is a restaurant well known in a metropolitan in South Africa called Mangaung for its giant burger. The restaurant has three branches. The first branch is in the Central Business District (CBD) of Bloemfontein, the second branch is in one of the leafy suburbs of Bloemfontein called Langenhoven park 2 (LHP) and the other is situated a bit out of Bloemfontein in Botshabelo (BOTS). The marginal costs and the price elasticity of demand for this giant burger for the three branches vary by seasons allowing for different pricing rules. The key aspect with Ozzy's is that all its branches enjoy market power. In fact, the marginal 1+Ep revenue (MR) for each of the branches can be represented by the expression: MR = P where P = price of the giant burger, and Ep = own price elasticity of demand for the branch's giant burger.
