Let M = the original amount
\n" ); document.write( "1st amount spent is 1/4M, so 3/4M remains
\n" ); document.write( "2nd amount spent is 1/5 of the remainder, or (1/5)(3/4M) = 3/20M.
\n" ); document.write( "The total amount spent is 1/4M + 3/20M = 8/20M = 2/5M.
\n" ); document.write( "3/5M = 66 -> M = $110
\n" ); document.write( "
\n" );
