Three friends need data for their online work and recreation and need to decide what speed to buy. Friend 1 is a low level user who needs only a speed of 5Mbps for research and reading. Friend 2 is an intermediate user who also does some computing. Friend 2 would find 10Mbps adequate. Friend 3 is a serious gamer who needs 20Mbps. Assume that they will split the account for the internet, that it is uncapped and that they will schedule their tasks so as not to interfere with each other's activities. The cost of a 5, 10 and 20 Mbps connection, is R300, R600 and R900 per month respectively. 3.1 Set up the characteristic function for the game.
