A woman made a deposit of $261. If her deposit consisted of 77 bills, some of them one-dollar bills and the rest being five-dollar bills, how many one-dollar bills did she deposit?
\n" ); document.write( ":
\n" ); document.write( "Let x = number of $1 bills; Let y = number of $5 bills
\n" ); document.write( ":
\n" ); document.write( "x + y = 77
\n" ); document.write( "y = (77 - x)
\n" ); document.write( ":
\n" ); document.write( "1x + 5y = 261
\n" ); document.write( ":
\n" ); document.write( "Substitute (77-x) for y in the above equation:
\n" ); document.write( "x + 5(77-x) = 261
\n" ); document.write( ":
\n" ); document.write( "x + 385 - 5x = 261
\n" ); document.write( ":
\n" ); document.write( "x - 5x = 261 - 385
\n" ); document.write( ":
\n" ); document.write( "-4x = -124
\n" ); document.write( ":
\n" ); document.write( "x = -124/-4
\n" ); document.write( ":
\n" ); document.write( "x = + 31 ea $1 bills
\n" ); document.write( ":
\n" ); document.write( "y = 77 - 31
\n" ); document.write( ":
\n" ); document.write( "y = 46 ea $5 bills
\n" ); document.write( ";
\n" ); document.write( ";
\n" ); document.write( "Check: 31 + 5(46) = $261
\n" ); document.write( " \n" ); document.write( "
\n" );
