Answer 2

Answer: Furniture over weeks

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
