The inverse proportional relationship that models this variation is given as follows:

<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
An inverse proportional relationship is given as follows:

In this problem, we have an inverse relation in which y(2) = 5000, hence the constant k is found as follows:


k = 10,000
Hence the relation is:

As stated in the problem, when x = 5, y = 2,000, which we can verify replacing in the relation.
