Answer:
The total producer and consumer surplus is $1.85 and $5.25 respectively
Explanation:
The computation of the producer and consumer surplus is shown below:
Producer surplus = Market price - Actual amount to sell the goods
For Jeff, The producer surplus = $5 - $4 = $1
For Samir, The producer surplus = $5 - $4.15 = $0.85
So, the total producer surplus = $1 + $0.85 = $1.85
And, the consumer surplus = Willing to pay - Market price
For Jeff, The producer surplus = $7.25 - $5 = $2.25
For Samir, The producer surplus = $8 - $5 = $3
So, the total producer surplus = $2.25 + $3 = $5.25
