Question

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?
a. p = b/k

b. p = k * b

c. p = k/b

d. p = k + b

Answer 1

Answer:
p = k/b

Explanation:
We are given that:
The number of painters (p) is inversely proportional to the time taken (b).
This means that as the number of painters increase, the time required to paint the building decreases and vice-versa.

This can be expressed using the following equation:
p = k/b
where k is the constant of proportionality

Hope this helps :)

Answer 2

The Answer is
c) p=k/b
