3.2. Consider the market for apples. If the price of oranges increases, then the (demand for / supply of) apples will (increase / decrease). If a new tax on apple production is introduced, then the (demand for / supply of) apples will (increase / decrease). If these effects happen together, then graph (A/B/C/D) illustrates this situation and the effect on equilibrium price will be (an increase / a decrease / indeterminate) and the effect on equilibrium quantity will be (an increase / a decrease / indeterminate)
