Answer:
D
Step-by-step explanation:
Willingness to pay is the highest amount a consumer is willing to pay for a good or service. A consumer would purchase a good as long as price is equal to or less than their willingness to pay.
Consumer surplus is the difference between the willingness to pay of a consumer and the price of the good.
Consumer surplus = willingness to pay – price of the good
People would purchase a good as long as consumer surplus is positive or zero
Michael = $500 - $300 = $200
Earvin = $400 - $300 = $100
Larry = $350 - $300 = $50
Charles = $300 - $300 = 0
