Money spent on advertising is money spent as well as any I know of
花在广告上的钱和我所知道的一样多
know of 这里是 “所了解的,所知道的”,不能省略of.
用英语解释 know of = be aware of the existence of someone or something. 它和 know 不一样, know表示认识、知道 （具体的事和人）.
as well as 这里是副词,表示 “也、一样”的意思.
Money (spent on advertising ）spent on advertising是从句修饰money
is money spent as well as any I know of
