For most of the years, a rough estimate of 1/5 of the per capita income is sufcient for the comparison to the revenue per student. For the years 1930, 1940, 1950, and 1960, you might estimate 1/5 of the per capita incomes as $1,300, $1,400, $2,000, and $2,500, respectively, which are clearly greater than the corresponding revenues per student.
For 1980 and 1990, your estimates might be $4,000 and $5,000, which are less than the corresponding revenues per student.
For 1970, you do have to calculate \(\frac{$17,340}{5} = $3,468\), which is greater than $3,440. So the revenue per student was less than 1/5 of the per capita income for the fve years 1930, 1940, 1950, 1960, and 1970. The correct answer is Choice E.
