We would need to see the graph, but the equilibrium point is where the wage paid is equal to the supply of workers. On a graph, this would be the point where the two lines intersect. That is the point where the supply of people willing to do the job at a certain rate, meets the company's demand for workers and the rate they are willing to pay.
Answer:

Explanation:
We want to know the value of
when 

From here, we can find the factors of the quadratic equation, we need two numbers that multiplied give -400 and added -30. Since they are factors of 400, we can choose -20x20 or -40x10. When adding -20 and 20 the result is zero, but the sum of -40 and 10 is -30. Then:

The solutions of the quadratic equation are
and
:

Since
is a positive integer:
