Tammy earned a total of $210 over 3 days.
\n" ); document.write( "Each day she earned twice as much as she did on the previous day.
\n" ); document.write( "How much did she earn on each of the 3 days?
\n" ); document.write( "------------------------
\n" ); document.write( "Let \"x\" be amount earned on day one
\n" ); document.write( "2x is the amount earned on day two
\n" ); document.write( "4x is amount earned on day three
\n" ); document.write( "----------------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "x + 2x + 4x = 210
\n" ); document.write( "7x = 210
\n" ); document.write( "x = 30 (1st day
\n" ); document.write( "2x = 60 (2nd day
\n" ); document.write( "6x = 120 (3rd day
\n" ); document.write( "-----------------------
