Lets deal in inches to make things simple to start with:\r
\n" ); document.write( "\n" ); document.write( "Let x=Dana's adult height\r
\n" ); document.write( "\n" ); document.write( "4ft 8in=48+8=56in--------------Dana's height at the age of 10\r
\n" ); document.write( "\n" ); document.write( "Now we are told that:\r
\n" ); document.write( "\n" ); document.write( "56 in is 84.4% of x------------So:
\n" ); document.write( "0.844x=56 divide both sides by 0.844\r
\n" ); document.write( "\n" ); document.write( "x=66.3507 in-----------------------Dana's adult height
\n" ); document.write( "66.3507/12=5.529 ft or 5ft 6.3in\r
\n" ); document.write( "\n" ); document.write( "NOW LETS LOOK AT IT YOUR WAY:\r
\n" ); document.write( "\n" ); document.write( "Her adult height (x) minus her height at 10 years old (56) equals = the amount that she grew and that equals 15.6% of her adult height\r
\n" ); document.write( "\n" ); document.write( "x-56=0.156x and this turns out to be the same equation as before\r
