5 dollar worth (?)

[Sweetpumpkin]

Hello,

I have a question on the sentence below:

I want to put in 5 dollar worth of gas.

I think "5 dollar" here should be changed to: 5-dollar or 5 dollars'. Do you think I'm right? Are there any possible changes? Please let me know.

Thank you in advance,
sweetpumpkin

Hi,
As is often with English grammar, there are some party-poopers\naysayers coming up with an alternative:
http://english.stackexchange.com/questions/25749/thousand-dollars-worth-or-thousand-dollars-worth-is-this-a-possessive

P.S. It's true about "Two Weeks Notice"--you can find it both with\without an apostrophe. In abundance.

Since it is not five dollars, but gas worth five dollars that he wants to put in, I think 'five-dollar worth' or 'five dollars' worth' should be more acceptable as suggested by the poster.

As you say, there is a growing tendency to drop the apostrophe and write the phrases as 'two weeks notice', 'medicos association', 'senior citizens forum' etc.

I disagree that the singular form of 'dollar' would work here (however you choose to view it 'five' requires a plural), however else you choose to punctuate it (and in modern use, as noted, there is a lot of flexibility with regard to the punctuation).

Flexibility is welcome when there is no confusion about comprehending the meaning the writer wants to convey.
