Melissa buys an iPhone for $240 and gets consumer surplus of $160.
1. .What is her willingness to pay?
2. If she had bought the iPhone on sale for $180, what would her consumer surplus have been?
3. What happens to her consumer surplus if the price of an iPhone was $500?
Since the consumer surplus is the area below the demand curve and above the price. In other words, the consumer surplus is the difference of maximum willingness to pay for any good and price of that good.
Demand curve shows the maximum willingness to pay for any goods or services.
CS= maximum willingness to pay- actual price
160= maximum willingness to pay- 240
maximum willingness to pay=160+240
=$400
2.
If she had bought the iPhone on sale for $180,
CS=400-180
=$220
3.
If the price of an iPhone was $500 and her maximum willingness to pay is $400, then Melissa will not purchase iPhone, so there will be no consumer surplus.
