.04x+.0225(33,000-x)=970
\n" ); document.write( ".04x+742.5-.0225x=970
\n" ); document.write( ".0175x=970-742.5
\n" ); document.write( ".0175x=227.5
\n" ); document.write( "x=227.5/.0175
\n" ); document.write( "x=13,000 amount invested @ 4%.
\n" ); document.write( "33,000-13,000=20,000 amount invested @ 2.25%
\n" ); document.write( "Proof:
\n" ); document.write( ".04*13,000+.0225*20,000=970
\n" ); document.write( "520+450=970
