You can put this solution on YOUR website!
Let \"x\"= original money he got
\n" ); document.write( "So, if he lost 30%: --------> [x-30%x=$3500], working eqn
\n" ); document.write( "Continuing,
\n" ); document.write( " $\"x%281-0.30%29=3500\"$ -----> $\"x%280.70%29=3500\"$
\n" ); document.write( " $\"x%2Across%280.70%29%2Fcross%280.70%29=cross%283500%295000%2Fcross%280.70%29\"$
\n" ); document.write( " $\"x=5000\"$ ----------> original money he has
\n" ); document.write( "In checking, we'll go back, losing 30%:
\n" ); document.write( "$5000-30%($5000)
\n" ); document.write( "$5000(1-0.30)
\n" ); document.write( "$5000(0.70)
\n" ); document.write( "$3500
\n" ); document.write( "Thank you
