Answer:
Abdul's surplus= $400
Total surplus=$500
Explanation:
Consumer surplus can be defined as the amount a consumer is willing to pay and the amount he actually paid (which is usually less).
Given:
Carolina willing selling price=$2,000
Abdul willing buying price=$2,500
Abdul negotiated price=$2,100
Abdul is willing to pay $2,500 but he negotiated $2,100
Abdul's surplus= $2,500-$2,100
=$400
Total surplus= Abdul's willing price - carolilina's willing price
Total surplus= $2,500 - $2,000
= $500
