The following is a demand schedule for cheeseburgers for an individual.
Plot the demand curve for cheeseburgers, with price on the Y-axis, and quantity demanded per week on the X-axis.
| PRICE OF CHEESEBURGERS | QUANTITY DEMANDED |
| 5.00 | 0 |
| 4.50 | 1 |
| 4.00 | 2 |
| 3.50 | 3 |
| 3.00 | 4 |
| 2.50 | 5 |
| 2.00 | 6 |
| 1.50 | 7 |
| 1.00 | 8 |
| 0.50 | 9 |
- Plot the demand curve for cheeseburgers, with price on the Y-axis, and quantity demanded per week on the X-axis.
- 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.
- Assuming chicken and cheeseburgers are perfect substitutes, and income is fixed at £24, what is likely to happen to the demand for chicken burgers (to the nearest burger) if the price of cheeseburgers rises to £4.00?
