Explanation:
We use many for countable nouns: days, bottles of apple juice, dollars.
We use much for uncountable nouns: time, apple juice, money.

Example:
The cat drinks a lot of milk, but the dog doesn't drink much milk.
The monkey eats a lot of bananas, but the donkey doesn't eat many bananas.

Complete the sentences according to the example:
He has got a lot of money, but she hasn’t got money.
They have read books, but we haven't read books.
She bought food, but they didn’t buy food.
I have got luggage, but you haven’t got luggage.
We know people, but you don’t know people.
She’ll take pictures, but he won’t take pictures.

Now use only much and many:

Does she drink coffee?
He doesn’t have friends.
They didn’t tell us about their school trip.
I don’t like him very .
