Pembahasan Ujian PAI: A30 – No. 20 – November 2010

Fungsi Penawaran:
\({Q_1} = 2\) \({P_1} = 3\) \({Q_2} = 16\) \({P_2} = 10\)

• \(\frac{{Q – {Q_1}}}{{{Q_2} – {Q_1}}} = \frac{{P – {P_1}}}{{{P_2} – {P_1}}}\)
• \({Q_d} = {Q_s}\)

Fungsi Penawaran:
\(\frac{{Q – {Q_1}}}{{{Q_2} – {Q_1}}} = \frac{{P – {P_1}}}{{{P_2} – {P_1}}}\) \(\frac{{Q – 2}}{{16 – 2}} = \frac{{P – 3}}{{10 – 3}}\) \(\frac{{Q – 2}}{{14}} = \frac{{P – 3}}{7}\) \(Q = 2P – 4\) \({Q_d} = {Q_s}\) \(– 5P + 45 = 2P – 4\) \(P = 7\)
