D+P=850 OR D=850-P
\n" ); document.write( "300D+225P=217,500 NOW SUBSTITUTE (850-P) FOR D IN THIS EQUATION & SOLVE FOR P:
\n" ); document.write( "300(850-P)+225P=217,500
\n" ); document.write( "255,000-300P+225P=217,500
\n" ); document.write( "-75P=217,500-255,000
\n" ); document.write( "-75P=-37,500
\n" ); document.write( "P=-37,500/-75
\n" ); document.write( "P=500 NUMBER OF PONDEROSA PINE TREES
\n" ); document.write( "850-500=350 NUMBER OF DOUGLAS FIRS.
\n" ); document.write( "PROOF
\n" ); document.write( "300*350+225*500=217,500
\n" ); document.write( "105,000+112,500=217,500
