For example:

He had two-hundred dollars.

He lived for one-hundred years.

I have never put a hyphen before hundred in situations like those, but according to this (unsure of its reliability, however), it says:

. . . one-hundred dollars is hyphenated because one-hundred is a compound adjective standing before dollars . . .

From the example since "xxx-hundred" is modifying something (dollars/years), making it an adjective, should I therefore put a hyphen in between?

It is not an adjective in those expressions, and is not normally hyphenated. Your source is wrong in describing it as an adjective.

It is a quantifier, which is grammatically quite different from an adjective.

On the other hand, suppose a casino has chips of different denominations, one of which is 100. Then one might speak about "a one-hundred chip": in this phrase, it would be adjectival, and so hyphenated. This is quite different from "one hundred chips".


Well, all the compound numbers between 21 and 99 are hyphenated. There are some rules to write numbers with hyphens.

Said that...

Thirty two - incorrect
Thirty-two - correct.

The rule also applies if a number between 21 and 99 is being used as an adjective (Grammarly Handbook). So, in your case, it would be...

...two hundred dollars
....one hundred years


Twenty-five hundred dollars.

Also, note this -

Six thousand and seventy-two
