3 ties cost $28. (Note the '$' is placed in front of the value.)
\n" ); document.write( ".
\n" ); document.write( "3 ties could be defined: a, b, c.
\n" ); document.write( ".
\n" ); document.write( "one tie was twice as much as one of the others
\n" ); document.write( "b = 2a
\n" ); document.write( ".
\n" ); document.write( "the remaining tie cost $24
\n" ); document.write( "c = 24
\n" ); document.write( ".
\n" ); document.write( "a +2a + 24 = 28
\n" ); document.write( "3a = 4
\n" ); document.write( "a = 4/3
\n" ); document.write( "a = $1.33
\n" ); document.write( ".
\n" ); document.write( "b = 2a
\n" ); document.write( "b = 8/3
\n" ); document.write( "b = $2.67
\n" ); document.write( ".
\n" ); document.write( "Check your work.
\n" ); document.write( "a + b + c = ?
\n" ); document.write( "24 + 1.33 + 2.67 = 24 + 4 = 28
\n" ); document.write( "Correct.
\n" ); document.write( ".
\n" ); document.write( "The two other ties costs $1.33 and $2.67 each.
\n" ); document.write( ".
\n" ); document.write( "Notice that I rounded 4/3 to 1.33 and, to make the total = $4, I rounded 8/3 to 2.67.
\n" ); document.write( ".
\n" ); document.write( "Done.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
