\n" ); document.write( " $\"x\"$ = amount invt. @4%
\n" ); document.write( " $\"33000-x\"$ = amount invt. @2.25%
\n" ); document.write( "Therefore,
\n" ); document.write( " $\"0.04x%2B0.0225%2833000-x%29=970\"$ , eqn 1
\n" ); document.write( " $\"0.04x%2B742.50-0.0225x=970\"$
\n" ); document.write( " $\"0.0175x=970-742.50=227.50\"$
\n" ); document.write( " $\"cross%280.0175%29x%2Fcross%280.0175%29=cross%28227.50%2913000%2Fcross%280.0175%29\"$
\n" ); document.write( " $\"x=13000\"$ --------------> amount invt. @4%
\n" ); document.write( " $\"33000-13000=20000\"$ -----------> amount invt. @2.25%
\n" ); document.write( "Check via eqn 1,
\n" ); document.write( " $\"0.04%2813000%29%2B0.0225%2820000%29=970\"$
