The demand equation for the Drake GPS Navigator is: x + 4p - 1100 = 0,
\n" ); document.write( "where x is the quantity demanded per week and p is the wholesale unit price in dollars.
\n" ); document.write( ":
\n" ); document.write( " The supply equation
\n" ); document.write( "x - 21p + 1000 = 0,
\n" ); document.write( "where x is the quantity the supplier will make available in the market each week when the wholesale price is p dollars each.
\n" ); document.write( ":
\n" ); document.write( " Find the equilibrium quantity and the equilibrium price for the GPS Navigators.
\n" ); document.write( "equilibrium quantity= units
\n" ); document.write( "equilibrium price $=
\n" ); document.write( ":
\n" ); document.write( "Equilibrium occurs when demand = supply, therefore
\n" ); document.write( "x + 4p - 1100 = x - 21p + 1000
\n" ); document.write( "Subtract x from both sides
\n" ); document.write( "4p - 1100 = -21p + 1000
\n" ); document.write( "4p + 21p = 1000 + 1100
\n" ); document.write( "25p = 2100
\n" ); document.write( "p = 2100/25
\n" ); document.write( "p = $84 equilibrium prices
\n" ); document.write( ";
\n" ); document.write( "Find x using the demand equation
\n" ); document.write( "x + 4(84) - 1100 = 0
\n" ); document.write( "x + 336 - 1100 =
\n" ); document.write( "x - 764 = 0
\n" ); document.write( "x = 764 units equilibrium qty
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solutions in the supply equation; x -21p + 1000 = 0
\n" ); document.write( "764 - 21(84) + 1000 = 0
\n" ); document.write( "764 - 1764 + 1000 = 0
