   Prob 10 9. In 1798, Thomas Malthus’s Essay on the Principle of Population was published. In it, he wrote: “Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio…. This implies a strong and constantly operating check on population from the difficulty of subsistence.” Malthus was saying that the growth of the population is limited by the amount of food available to eat; people will live at the subsistence level forever. Why didn’t Malthus’s description apply to the world after 1800?

    Prob 10 10. College tuition has risen significantly in the last few decades. From the 1979–1980 academic year to the 2009–2010 academic year, total tuition, room, and board paid by full-time undergraduate students went from $2,327 to $15,041 at public institutions and from $5,013 to $35,061 at private institutions. This is an average annual tuition increase of 6.4% at public institutions and 6.7% at private institutions. Over the same time, average personal income after taxes rose from $7,956 to $35,088 per year, which is an average annual rate of growth of personal income of 5.0%. Have these tuition increases made it more difficult for the average student to afford college tuition?
