Suppose you want to analyze the level of foreign aid that Canada gives to developing countries each year. You are told that Canada's aid depends on the population of these countries, their level of poverty, and how good governance is in these countries (measured by absence of corruption, etc.) Indicating your notation, write this information:
i) As a general function.
ii) As a linear function.
iii) Comment on the likely sign of the coefficients in your linear function. ( Be sure to be clear; explain your line
of reasoning.)
