1. The problem statement, all variables and given/known data
Suppose that a new law requires every firm to provide its workers with free cell phones. The cell phones are worth $200 a year to the works and cost the firms$500 a year to provide. On a labor supply/demand curve, how do I know how much the equilibrium wage goes up or down after the law is enacted?

3. The attempt at a solution
I am assuming the equilibrium wage goes down between $200 and$500 dollars, but am not sure how to justify this mathematically?
