In the production of a product, a negative external effect
arises. This means that the total marginal cost of
manufacturing companies

𝑀𝐶𝑝 = 𝑄

differs from society's marginal cost, which is

𝑀𝐶𝑠 = 4𝑄.

To internalize the negative external effect, the state has decided
to introduce a tax
per unit produced. If the product's demand function is given
by

𝑄 = 50 −𝑝

how large should the tax be for the companies to produce the amount
of the product that
society wants?
