3 The directors of The Healthy Eating Group (HEG), a successful restaurant chain, which commenced trading in 1998,have decided to enter the sandwich market in Homeland, its country of operation. It has set up a separate operationunder the name of Healthy Sandwiches Co (HSC).

SFG insists that it selects the suppliersof the ingredients that are used in making the sandwiches it sells and therefore HSC would be unable to reducethe costs of the ingredients used in the sandwiches. HSC will be the sole supplier for SFG.(2) The number of sandwiches sold per year in Homeland is 625 million. SFG has a market share of 4%.(3) The average selling price of all sandwiches sold by SFG is $2·40.
