Answer:
Option D.
Step-by-step explanation:
Let as consider the function f(t) approximates how many pieces of furniture he paints per hour. It means unit of this function is furniture/hours.
The function w(h) represents how many hours per week Joey spends painting the pieces of furniture. It means unit of this function is hours/weeks.
We need to find the units of measurement for the composite function f(w(h)).
It the function f(w(h)), first we need to apply the function w(h) after that f(t).
[tex]f(w(h))=\frac{furniture}{hours}(\frac{hours}{week})[/tex]
[tex]f(w(h))=\frac{furniture}{week}[/tex]
The units of measurement for the composite function f(w(h)) is furniture/weeks.
Therefore, the correct option is D.
