we start with $50,000 and send $20,000 to charity. This leaves us with $30,000.
\n" ); document.write( "We use the formula = PRT + PRT to get
\n" ); document.write( "{{6060 = x(.16)(1) + (30000-x)(.25)(1)}}}
\n" ); document.write( "we get
\n" ); document.write( "\"6060+=+.16x+%2B+7500+-+.25x\"
\n" ); document.write( "and then
\n" ); document.write( "\"6060+=+7500+-.09x\"
\n" ); document.write( "subtract to get
\n" ); document.write( "\"-1440+=+-.09x\"
\n" ); document.write( "divide by -.09 to get
\n" ); document.write( "\"16000+=+x\"
\n" ); document.write( "So, we invest
\n" ); document.write( "16,000 at 16%
\n" ); document.write( "14,000 at 25%.
\n" ); document.write( "
\n" );
