Solution Steps

Step 1: Determine Enrollment at $25,000 Tuition
  • From the table, find the enrollment demanded when tuition is $25,000.
  • At $25,000 tuition, the enrollment demanded is 4 million students.
Step 2: Calculate Social Demand Curve
  • Society gets an external benefit of $5,000 for every enrolled student.
  • Adjust the tuition values by subtracting $5,000 to reflect the social benefit.
  • New tuition values for social demand curve:
    • $40,000 - $5,000 = $35,000
    • $35,000 - $5,000 = $30,000
    • $30,000 - $5,000 = $25,000
    • $25,000 - $5,000 = $20,000
    • $20,000 - $5,000 = $15,000
    • $15,000 - $5,000 = $10,000
    • $10,000 - $5,000 = $5,000
    • $5,000 - $5,000 = $0
Step 3: Plot Market and Social Demand Curves
  • Plot the market demand (DM) curve using the original tuition and enrollment data.
  • Plot the social demand (DS) curve using the adjusted tuition values and the same enrollment data.

Final Answer

  • At $25,000 tuition, 4 million students will enroll.
  • The market demand (DM) curve points are:
    • (1, 40)
    • (2, 35)
    • (3, 30)
    • (4, 25)
    • (5, 20)
    • (6, 15)
    • (7, 10)
    • (8, 5)
  • The social demand (DS) curve points are:
    • (1, 35)
    • (2, 30)
    • (3, 25)
    • (4, 20)
    • (5, 15)
    • (6, 10)
    • (7, 5)
    • (8, 0)
