If the total weekly earnings of the workers with some college is $22,500,000 and the average weekly earnings of that cohort are $750, then there are 22,500,000/750=30,000 such workers. Refer to the second graph to see that these 30,000 people make up one-quarter of the workforce in City D, so the total workforce there is 4 × 30,000 = 120,000. Full-time workers with less than a high school education are 5% of that total, which is 120,000 × 0.05 = 6,000 people. Since this category of workers earns $500 per week, their total weekly earnings are 6,000 × $500 = $3,000,000. (D) is correct.
