(1995-1990)/(3200-1500)=(2009-1990)/(X-1500)
\n" ); document.write( "5/1700=19/(X-1500
\n" ); document.write( "5(X-1500)=19*1700
\n" ); document.write( "5X-7500=32300
\n" ); document.write( "5X=32300+7500
\n" ); document.write( "5X=39800
\n" ); document.write( "X=39800/5
\n" ); document.write( "X=$7,960 IS THE PROJECTED TUITION FOR 2009.
