Joey paints old furniture and sells the pieces at craft fairs. The function f (t) approximates how many pieces of furniture he paints per hour. The function w (h) represents how many hours per week Joey spends painting the pieces of furniture. What are the units of measurement for the composite function f (w (h)) ?

hours over weeks

weeks over furniture

furniture over hours

furniture over weeks

Answer: Furniture over weeks

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

f (t) = furniture / hour w (h) = hours/week

So, for the function f (w (h)) = hours / week x (furniture / hours)

Because "hours" are in both terms, and one is the numerator and the other is the denominator, they can be cancelled with each other.

f (w (h)) = furniture / week
