Answer:
A. $60
Explanation:
Recall that, consumer's surplus refers to the price that a consumer is willing to pay less the amount he or she actually pays.
Thus
Consumer surplus = maximum price willing to pay - actual market price.
Given that
Market price = $40
Vonda is willing to pay = $90
Aleiyah is willing to pay = $50
Hence.
Vonda consumer surplus = 90 - 40
= $50
Aleiyah consumer surplus = 50 - 40
= $10.
Total consumer surplus = 50 + 10
= $60.
