Answer:
$12
Explanation:
Producer's surplus=1/2*Q*P( Just like the formula for the area of a triangle which is 1/2*base*height)
P is the price of the item which is $4
Q is the quantity bought and sold, which is 6 units in this case, hence, the producer surplus is shown thus
producer's surplus=1/2*$4*6
producer's surplus=$12
