LET KAREN HAVE AT THE BEGINNING……X ….HENCE SHE SPENT X-8……MONEY REMAINING =8
\n" ); document.write( "STORE 1…….SHE HAD AT START X …HALF OF IT =X/2…..2 LESS THAN THAT =0.5X-2…SO SHE SPENT =0.5X-2….REMAINING=X-0.5X+2=0.5X+2
\n" ); document.write( "STORE 2…….SHE HAD AT START 0.5X+2 …HALF OF IT =0.25X+1…..2 LESS THAN THAT =0.25X+1-2…SO SHE SPENT =0.25X-1….REMAINING=0.5X+2-0.25X+1=0.25X+3
\n" ); document.write( "STORE 3…….SHE HAD AT START 0.25X+3 …HALF OF IT =0.125X+1.5…..2 LESS THAN THAT =0.125X+1.5-2…SO SHE SPENT =0.125X-0.5….REMAINING=0.25X+3-0.125X+0.5=0.125X+3.5
\n" ); document.write( "HENCE WE HAVE ……0.125X+3.5=8….OR……..0.125X=4.5……….
