well there are two amounts we are dealing with here that total $33000. so we will call one amount x and the other 33000-x. the total of the two principal sums times there various interest rates will equal the interest earned.\r
\n" ); document.write( "\n" ); document.write( "so we have .04x+.0225(33000-x)=970 distribute the 2nd term and we get\r
\n" ); document.write( "\n" ); document.write( ".04x+742.50-.0225x=970 simply to .0125x=227.5 x=$18200 ... $33000-x=$14800\r
\n" ); document.write( "\n" ); document.write( "so Donna invested $18,200 at 4% and $14,200 at 2.25%
\n" ); document.write( "
\n" );
