Set P = number of parent tickets \n" ); document.write( "Set S = number of student tickets \n" ); document.write( "P + S = 200 \n" ); document.write( "P*$3.00 + S*$1.00 = $450.00 \n" ); document.write( "3P + S = 450 \n" ); document.write( "Add -S to each side of the equation P + S = 200 \n" ); document.write( "P = 200-S \n" ); document.write( "Substitute (200-S) for P in 3P + S = 450 \n" ); document.write( "3(200-S) + S = 450 \n" ); document.write( "600 -2S = 450 \n" ); document.write( "add -600 to each side \n" ); document.write( " -2S = -150 \n" ); document.write( "divide each side by 3 \n" ); document.write( " S = 75 \n" ); document.write( "Since P = 200-S \n" ); document.write( "P = 200-75 = 125 \n" ); document.write( "So 75 students at $1 plus 125 parents at $3 for a total of $450 \n" ); document.write( " |
