Let $\"n\"$ be the 3-digit number, and the value of the number.
\n" ); document.write( "Placing a $\"4\"$ at the end of that 3-digit number turns it into
\n" ); document.write( "a 4-digit number whose value is $\"10n%2B4\"$ .
\n" ); document.write( "If doing that incleases the value by $\"4828\"$ , then
\n" ); document.write( " $\"10n%2B4-n=4828\"$ ---> $\"9n%2B4=4828\"$ ---> $\"9n=4828-4\"$ ---> $\"9n=4824\"$ ---> $\"n=4824%2F9\"$ ---> $\"highlight%28n=536%29\"$ . \n" ); document.write( "
