\n" );
document.write( "Let amount borrowed at 13% be T
\n" );
document.write( "Since the amount borrowed at 16% was $200 more than twice the amount borrowed at 13%, then amount borrowed
\n" );
document.write( "at 16% = 2T + 200
\n" );
document.write( "Annual interest paid on 13% loan = .13(T), or .13T
\n" );
document.write( "Annual interest paid on 16% loan = .16(2T + 200), or .32T + 32
\n" );
document.write( "As total annual interest paid was $234.5, we get: .13T + .32T + 32 = 234.5
\n" );
document.write( ".13T + .32T = 234.5 - 32
\n" );
document.write( ".45T = 202.5
\n" );
document.write( "T, or amount borrowed at 13% = , or $
\n" );
document.write( "Amount borrowed at 16% = 2(450) + 200, or 900 + 200, or $ \n" );
document.write( "

\n" );
