average weekly = total weekly/# people
total weekly = 22.5mil, average weekly is 750 as shown in top graph
Thus the number of people is 30,000.
Now, we can extrapolate from the second graph that the number of people in city D is 120,000 because we expect that 25% of the people in city D with some college is 30,000 people.
.25x = 30000
x = 120,000 which is the total number of people in city D
Now,
.05(120000) = 6000 people with less than HS education worked in city D.
Once more, using avg = total/# people we have
avg = 500 = total/6000
total = 3 mil
