Dave borrowed $25000 in total from two banks. The first bank charged him 6% per annum while the second charged 9% per annum. At the end of the first year he paid equal amounts of interest to each bank. Determine the amount borrowed at each rate?
\n" ); document.write( "---------------
\n" ); document.write( "Let amt borrowed at 6% be \"x\"; Interest is 0.06x dollars
\n" ); document.write( "--------------
\n" ); document.write( "Amt borrowed at 9% is \"25000-x\"; interest is 0.09(25000-x)
\n" ); document.write( "---------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "Interest = Interest
\n" ); document.write( "0.06x = 0.09(25000-x)
\n" ); document.write( "6x = 9(25000-x)
\n" ); document.write( "6x = 225000-9x
\n" ); document.write( "15x = 225000
\n" ); document.write( "x = $15000 (amt borrowed at 6%)
\n" ); document.write( "25000=15000=$10000 (amt borrowed at 9%)
\n" ); document.write( "=========================
