# As much as - as many as

Can anyone help me with this question about Error Identification.

As many as 50 percent of the income from motion pictures produced in the United States comes from the films abroad.

The key is "As many as". Explanation for this is that "As much as" should be used here because "income" is an uncountable noun. Am I right?

Income can be countable or uncountable depending on the context and use.

The salaries of both partners amounted to a substantial family income

or

Taking into consideration the incomes of the two brothers, the loan company agreed to give them a mortgage.

But this is beside the point because it's not income that's being compared but the percentage.

When talking about percentages, proportions or money in general, we use much

As much as 50%

As much as half of what they earned

As much as a million dollars

On the other hand, we use many when considering individual units:

As many as 50 parts in 100

As many as a million dollar notes were printed that day.

• You do everything except explain which one is correct in this specific sentence...

• @Catija I thought As much as 50% did the job! May 30, 2017 at 17:23

Since your example is talking about an amount, 50% and not the number/count of income

as much as

is correct.
