Since Dr. Johnson's labor income is taxed at a rate of 40% above $100 per week, his budget line will have a kink at the point where his income is $200 (which is above $100) and his leisure is 60 units. Below this point, his budget line will have a slope of -1 (since each additional unit of leisure means one less unit of income), while above this point the slope will be -0.6 (since each additional unit of leisure means only 60 cents less in income). This creates a kink in the budget line.
