The number of painters p employed to paint a building is inversely proportional to the time taken to paint the building b which equation best models the number of painters required to finish the painting

p = k/b

Explanation:
We are given that:
number of painters (p) is inversely proportional to the time taken to paint the building (b).
This means that as p increases, b decreases and vice versa.
Therefore, the best equation to model this is:
p = k/b
where k is the constant of proportionality.

Hope this helps :)
