Solve the problem.
-Suppose that P(x) represents the percentage of income spent on housing in year x and I(x) represents income in year x. Determine a function H that represents total housing expenditures in year x.
A) H(x) = (P · I)(x)
B) H(x) = (P + I)(x)
C) $$\mathrm { H } ( \mathrm { x } ) = \left( \frac { \mathrm { I } } { \mathrm { P } } \right) ( \mathrm { x } )$$
D) H(x) = (I - P)(x)

Quizplus · Accepted Answer

H(x) = (P · I)(x) correctly represents total housing expenditures in year x because it multiplies the percentage of income spent on housing (P(x)) by the income (I(x)) to get the total amount spent on housing.

Solve the Problem H(x)=(IP)(x)\mathrm { H } ( \mathrm { x } ) = \left( \frac { \mathrm { I } } { \mathrm { P } } \right) ( \mathrm { x } )H(x)=(PI​)(x)

Solve the Problem $\mathrm { H } ( \mathrm { x } ) = \left( \frac { \mathrm { I } } { \mathrm { P } } \right) ( \mathrm { x } )$
