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

Multiple Choice

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)
