John took all his money from his savings account.

\n" ); document.write( "let a = original amt in the savings account
\n" ); document.write( ":
\n" ); document.write( "\"He spent $88 on a radio and 1/4 of what was left on presents for his friends.\"
\n" ); document.write( "Therefore he kept 3/4 of what was left

\n" ); document.write( ":
\n" ); document.write( "John then put 4/11 of his remaining money into a checking account and donated the $420 that was left to charity.
\n" ); document.write( "a = $\"4%2F11\"$ ( $\"3%2F4\"$ a - 66) + 420
\n" ); document.write( "a = $\"3%2F11\"$ a - 24 + 420

\n" ); document.write( "a = $\"11%2F8\"$ *396
\n" ); document.write( "a = $544.50 originally in his saving acct
