a. Plot the demand curve for cheeseburgers, with price on the Y-axis, and quantity demanded per week on the X-axis.
b. Assume the individual has a fixed budget of £24 per week to spend on burgers, and the current price of cheeseburgers and chicken burgers is £3.00, and that a consumer buys 4 of each type of burger. Now assume that the price of cheeseburgers falls to £2. Using the concept of the ‘income’ and ‘substitution’ effect, explain why the demand for cheeseburgers rises to 6.
