May i ask for the answer for this question?
Prior to 1997, PepsiCo, a major soft drink company, had a restaurant division consisting of Kentucky Fried Chicken, Taco Bell, and Pizza Hut. The only cola beverage these restaurants served was Pepsi. Assume that the major reason PepsiCo owned fast food restaurants is an attempt to increase its share of the cola market. Under this assumption, some Pizza Hut patrons who order a cola at the restaurant and are told they are drinking a Pepsi will switch and become Pepsi drinkers instead of Coke drinkers on other purchase occasions. However, studies have shown that some customers refuse to eat at restaurants unless they can get a Coke.
PepsiCo sells Pepsi Cola to non-PepsiCo restaurants at RM0.53 per gallon. This is the market price of Pepsi-Cola. Pepsi-Cola’s variable manufacturing cost is RM0.09 per gallon and its total (fixed and variable) manufacturing cost is RM0.22 per gallon. PepsiCo produces Pepsi-Cola in numerous plants located around the world. Plant capacity can be added in small increments (e.g., a half-million gallons per year). The cost of additional capacity is approximately equal to the fixed costs per gallon of RM0.13.
