Part I 5.00% per annum ------------- Amount invested =x
\n" ); document.write( "Part II 2.00% per annum ------------ Amount invested = y
\n" ); document.write( " 2500
\n" ); document.write( "Interest----- 95
\n" ); document.write( "
\n" ); document.write( "Part I 5.00% per annum ---x
\n" ); document.write( "Part II 2.00% per annum ---y
\n" ); document.write( "Total investment
\n" ); document.write( "x + 1 y= 2500 -------------1
\n" ); document.write( "Interest on both investments
\n" ); document.write( "5.00% x + 2.00% y= 95
\n" ); document.write( "Multiply by 100
\n" ); document.write( "5 x + 2 y= 9500.00 --------2
\n" ); document.write( "Multiply (1) by -5
\n" ); document.write( "we get
\n" ); document.write( "-5 x -5 y= -12500.00
\n" ); document.write( "Add this to (2)
\n" ); document.write( "0 x -3 y= -3000
\n" ); document.write( "divide by -3
\n" ); document.write( " y = 1000
\n" ); document.write( "Part I 5.00% $ 1500
\n" ); document.write( "Part II 2.00% $ 1000
\n" ); document.write( "
\n" ); document.write( "CHECK
\n" ); document.write( "1500 --------- 5.00% ------- 75.00
\n" ); document.write( "1000 ------------- 2.00% ------- 20.00
\n" ); document.write( "Total -------------------- 95.00
