Suppose that the price of a cashmere sweater is $100 and Jean's marginal benefit from a cashmere sweater is $300. If Jean buys 1 cashmere sweater, what is her consumer surplus? Jean's consumer surplus is $nothing

$200

Explanation:

Given that,

Price of sweeter = $100

Marginal benefit from sweeter = $300

Recall that

Consumer surplus refers to the marginal benefits gotten from a good in excess of the price of paid for that good, summed over the total quantity of goods bought.

Since only one sweeter was bought

Thus,

Consumer surplus = (marginal benefit - price) ÷ quantity bought

= (300 - 100) ÷ 1

= $200

hope i explained myself
