\n" ); document.write( "Let's appoint the 2 savings accounts as $\"S%5BA%5D\"$ & $\"S%5BB%5D\"$ .
\n" ); document.write( " $\"S%5BA%5D=x\"$ , money put down on $\"A\"$ account with 2% Annual Interest
\n" ); document.write( " $\"S%5BB%5D=13500-x\"$ ,money put down on $\"B\"$ account with 3% Annual Interest
\n" ); document.write( "So,
\n" ); document.write( " $\"0.02x%2B0.03%2813500-x%29=352.70\"$ ---------------------> working eqn
\n" ); document.write( " $\"0.02x%2B405-0.03x=352.70\"$
\n" ); document.write( " $\"405-352.70=0.03x-0.02x\"$
\n" ); document.write( " $\"52.3=0.01x\"$ ----> $\"cross%2852.3%295230%2Fcross%280.01%29=cross%280.01%29x%2Fcross%280.01%29\"$
\n" ); document.write( " $\"x=5230\"$ -----------------------> Amount invested on $\"S%5BA%5D\"$
\n" ); document.write( " $\"13500-5230=8270\"$ --------------> Amount invested on $\"S%5BB%5D\"$
\n" ); document.write( "In doubt? go back working eqn:
\n" ); document.write( " $\"0.02%285230%29%2B0.03%288270%29=352.70\"$
\n" ); document.write( " $\"104.60%2B248.10=352.70\"$
\n" ); document.write( " $\"352.70=352.70\"$
\n" ); document.write( "Thank you,
