Juan offers tutoring services in the summer for elementary school students. Suppose that four potential tutoring clients are considering Juan's tutoring services for their children. Ms. Jackson is willing to pay $20 per hour; Ms. Lopez is willing to pay $22 per hour; Mr. Jordan is willing to pay $18 per hour and Mr. Singh is willing to pay $20 per hour. If Juan charges $19 per hour for his tutoring services, what will be the consumer surplus, considering the four families combined?
