Answer 1

Answer:

$13

$9

Explanation:

Total surplus is the sum of consumer surplus and producer surplus.

Consumer surplus is the difference between the willingness to pay of a consumer and the price he pays for the good.

Consumer surplus = willingness to pay - price of the good

Producer surplus is the difference between the least amount a seller is willing to sell his product and the price he sells the product.

Producer surplus = price of the good - least price the seller is willing to sell his product

Total surplus = consumer surplus + producer surplus

Total surplus = willingness to pay - price of the good + price of the good - least price the seller is willing to sell his product

Prices cancel out

Total surplus = willingness to pay - least price the seller is willing to sell his product

A. Total surplus = $18 - $5 = $13

B. Total surplus = $16 - $7 = $9
