A Broadway theater was 500 seats, divided into orchestra, main, and balcony
\n" ); document.write( "Quantity Equation: r + m + b = 500
\n" ); document.write( "------------------------------------------\r
\n" ); document.write( "\n" ); document.write( "seating. Orchestra sells at $80, Main sells at $70, and Balcony sells at $40. If all seats are sold out, and the gross revenue to the theater is $30,900.
\n" ); document.write( "Value Equation: 80r + 70m + 40b = 30,900
\n" ); document.write( "---------------------------------------------------\r

\n" ); document.write( "\n" ); document.write( "If all the main and balcony are sold out, and only half the orchestra are sold, the gross revenue is $26,900.
\n" ); document.write( "Value equation: (1/2)80r + 70m + 40b = 26,900

\n" ); document.write( "----------------------------------------------
\n" ); document.write( "Rearrange the three equations and solve the system by any means to get:
\n" ); document.write( "r = 100
\n" ); document.write( "m = 230
\n" ); document.write( "b = 170
