A manufacturing company has a policy that states managers are paid a salary that is proportional to the number of employees they
user100 [1]
From the problem description, we can construct an algebraic equation for the situation. Let S be the salary and x be the number of employees.

S = kx
where k is the proportionality constant

Using variation,

k = S₁/x₁ = S₂/x₂

Substituting,

34000/12 ? 36000/16
2833.33 ? 2250
Thus,
2833.33 ≠ 2250
<em>It does not follow the company's policy.</em>
