"How much did you spend?"
You have to use much because there is nothing countable here.
Many can be used when it's clear what you spent:
"How many dollars did you spend?"
You can count the dollars.
"How many hours did it take until it got finished?"
You can count the hours.
P.S: Again: Just my opinion!
Edit
Oh, now I see the thread was 1,5 years old...
Cheers!
For uncountable words we use "much".
For countable words we use "many".
Is it right or wrong? - It is right!
Thank you so much! - No problem!
Many people learn English here.

Well, I wouldn't call myself an expert, but I suppose it is a relative term.
Do you think this forum has been helpful so far? Do you think you are using English more effectively because of it?
I make plenty of mistakes myself. Please point them out when you see them. :wink:
You are welcome always.
I think we should put a accountable noun to be modified after 'how many' like this:
How many hours do you spend ?
