Final answer:
The cost of five purses in a monopoly is $4000, but without the price in a perfect competition, we cannot compare the difference. We need the pricing from the perfectly competitive market to calculate how much Jackie would pay comparatively.
Step-by-step explanation:
The student's question involves comparing the total cost of five purses in a perfect competition market versus a monopoly. Under monopoly conditions, given the provided information, Jackie would pay 5 x $800 = $4000 for the purses. Unfortunately, there's no direct information about the cost of purses in a perfectly competitive market within the provided text. We need this to accurately calculate the difference in cost that Jackie would pay between the two market structures.
Since we don't have the price of the purses in a perfectly competitive market, we can't complete the comparison to determine how much more or less Jackie would pay in a perfect competition compared to a monopoly. To provide an accurate answer, we would require data or a graph that shows the price of purses in a perfectly competitive market.
