Quizplus · Accepted Answer

The function for total housing expenditures should be the product of the percentage of income spent on housing and the income. Therefore, the correct formula is H(x) = P(x) * I(x), which is represented by choice A. None of the other options correctly represent this relationship. To find total housing expenditures, we need to multiply the percentage of income spent on housing by the income in that year. Therefore, choice A, H(x) = (P · I)(x), represents the correct function for total housing expenditures.
