You can put this solution on YOUR website!
I am assuming you made an error, the amount should be $550.00, not $55.00\r
\n" ); document.write( "\n" ); document.write( "(x)(.04) + (15000 - x)(.03) = 550\r
\n" ); document.write( "\n" ); document.write( ".04x + 450 - .03x = 550\r
\n" ); document.write( "\n" ); document.write( ".01x = 100\r
\n" ); document.write( "\n" ); document.write( "x = 10000\r
\n" ); document.write( "\n" ); document.write( "10000(.04) = 400
\n" ); document.write( "5000(.03) = 150\r
\n" ); document.write( "\n" ); document.write( "check 400 + 150 = 550.\r
