Math Problem Statement

Berikut ini merupakan fungsi demand dan supply: 𝑃 = 30 − 3𝑄 dan 𝑃 = 10 + 2𝑄.

(b)Fungsi supply baru setelah pajak diberlakukan. (c)Market equilibrium setelah pajak. (d)Bagian dari pajak yang dibayar oleh konsumen dan produsen, serta total pajak yang diterima oleh pemerintah. (e)Gambarkan kurva supply dan demand sebelum dan sesudah pajak.
