Jason needs help getting ready for the next test in his economics course and would like to hire Maria, an economics tutor to help him

Jason is willing to pay $30 for the first hour of tutoring, $25 for the second, $20 for the third, $15 for the fourth, and $10 for the fifth. The equilibrium price for tutoring is $15 per hour. For how many hours of tutoring will Jason hire Maria? Why this amount of hours? What is Jason's consumer surplus, if any, from the tutoring? What is Maria's consumer surplus from the tutoring?

Jason will hire Maria for 4 hours of tutoring. At $15 per hour, the marginal benefit to Jason of the first 4 hours exceeds the price. But the marginal benefit from the fifth hour is less than the price and so Jason will not hire Maria for 5 hours. Jason's total consumer surplus is $30, the sum of $15 from the first hour plus $10 from the second plus $5 from the third plus $0 from the fourth. Maria has no consumer surplus in this market because she is the producer not the consumer.
