Let there be X D.Fir trees
\n" ); document.write( "Then there are 850-X Pine trees
\n" ); document.write( "The Fir trees cost $300 each so total = 300X
\n" ); document.write( "The pine trees cost 225 each so total cost = 225(850-X)
\n" ); document.write( "Sum total
\n" ); document.write( "300X+225(850-X) = 217500
\n" ); document.write( "Dividing on both sides with 75
\n" ); document.write( "4X+3(850-X) = 2900
\n" ); document.write( "4X+2550-3X = 2900
\n" ); document.write( "X+2550= 2900
\n" ); document.write( "Subtracting 2550 0n both sides
\n" ); document.write( "X = 350
\n" ); document.write( "which means there are 500 pine trees
\n" ); document.write( "
\n" );
