John, Kevin and Jane have $120.
\n" ); document.write( "j + k + a = 120
\n" ); document.write( ":
\n" ); document.write( "Jane has a third of what John has
\n" ); document.write( "a = $\"1%2F3\"$ j
\n" ); document.write( "or
\n" ); document.write( "j = 3a
\n" ); document.write( ":
\n" ); document.write( "and Kevin has twice as much as Jane.
\n" ); document.write( "k = 2a
\n" ); document.write( ":
\n" ); document.write( "Find how much Jane has using the 1st equation, replace j and k
\n" ); document.write( "3a + 2a + a = 120
\n" ); document.write( "6a = 120
\n" ); document.write( "a = 120/6
\n" ); document.write( "a = $20
\n" ); document.write( ":
\n" ); document.write( " How much money does, in dollars, does Kevin have?
\n" ); document.write( "k = 2a
\n" ); document.write( "k = 2(20)
\n" ); document.write( "k = $40 \n" ); document.write( "

\n" );
