Algebra.Com's Answer #849898 by CPhill(1959)![]() ![]() You can put this solution on YOUR website! Here's how to analyze the impact of the tax on the equilibrium price and revenue:\r \n" ); document.write( "\n" ); document.write( "**1. Find the original equilibrium:**\r \n" ); document.write( "\n" ); document.write( "* Set the supply and demand equations equal to each other: \n" ); document.write( " 0.09q + 50 = 0.07q + 65\r \n" ); document.write( "\n" ); document.write( "* Solve for q (equilibrium quantity): \n" ); document.write( " 0.02q = 15 \n" ); document.write( " q = 750\r \n" ); document.write( "\n" ); document.write( "* Substitute the value of q back into either the supply or demand equation to find P (equilibrium price): \n" ); document.write( " P = 0.09(750) + 50 \n" ); document.write( " P = 117.5\r \n" ); document.write( "\n" ); document.write( "**2. Incorporate the tax:**\r \n" ); document.write( "\n" ); document.write( "A tax of N1.50/unit increases the supply equation by that amount. The new supply equation is:\r \n" ); document.write( "\n" ); document.write( "P_taxed = 0.09q + 50 + 1.50 \n" ); document.write( "P_taxed = 0.09q + 51.5\r \n" ); document.write( "\n" ); document.write( "**3. Find the new equilibrium (after tax):**\r \n" ); document.write( "\n" ); document.write( "* Set the new supply equation equal to the original demand equation: \n" ); document.write( " 0.09q + 51.5 = 0.07q + 65\r \n" ); document.write( "\n" ); document.write( "* Solve for the new equilibrium quantity (q_taxed): \n" ); document.write( " 0.02q = 13.5 \n" ); document.write( " q_taxed = 675\r \n" ); document.write( "\n" ); document.write( "* Substitute q_taxed back into the *original* demand equation to find the price the *consumer* pays (P_consumer): \n" ); document.write( " P_consumer = 0.07(675) + 65 \n" ); document.write( " P_consumer = 112.25\r \n" ); document.write( "\n" ); document.write( "* The manufacturer receives the consumer price *minus* the tax: \n" ); document.write( " P_manufacturer = P_consumer - 1.50 \n" ); document.write( " P_manufacturer= 112.25 - 1.50 = 110.75\r \n" ); document.write( "\n" ); document.write( "**4.
