Answer:
$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
