There are 850 Douglas fir and ponderosa pine trees in a section of forest bought by Sawz Logging Co. The company paid an average of $300 for each Douglas fir and $225 for each ponderosa pine. If the company paid $217,500 for the trees, how many of each kind did the company buy?\r
\n" ); document.write( "\n" ); document.write( " x = number of Douglas fir trees
\n" ); document.write( " 850 – x = number of Ponderosa pine trees\r
\n" ); document.write( "\n" ); document.write( " 300x + 225(850 - x) = 217,500
\n" ); document.write( " 300x + 191,250 - 225x = 217,500
\n" ); document.write( " 75x + 191,250 = 217,500
\n" ); document.write( " - 191,250 - 191,250
\n" ); document.write( " ____________________________
\n" ); document.write( " 75x = 26,250 divide by 75
\n" ); document.write( " ___divide
\n" ); document.write( " 75x
\n" ); document.write( " x = 350 Douglas fir trees
\n" ); document.write( " 850 – x = 500 Ponderosa Pine trees
\n" ); document.write( " \n" ); document.write( "
