Answer:
Total producer surplus= $30
Explanation:
Producer surplus is the difference between the price a seller is willing to sell and the market price or actual price at which the item is bought. The producer surplus is the additional benefit the seller gets from a sale.
Consumer surplus= Market price - Price seller is willing to sell for
Marco is willing to sell at $15 hour
Kelly is willing to pay $30 per hour
Mike is willing to pay $20 per hour
Surplus from Kelly= 30- 15= $15
Surplus from Mike= 20- 15= $5
Total producer surplus= ($15*1 hour) + ($5 *3 hours)
Total producer surplus= 15 + 15= $30
