Okay, I feel like I’m losing my marbles. This should be an easy question. And yet…
When writing the following sentence, I know an apostrophe is needed:
"I’d like five dollars’ worth of gumballs, please."
All well and good. (Except for the buyer’s teeth–that’s a helluva lot of gumballs!) But what happens when the sentence doesn’t use the spelled-out form of the word, but instead the numbers?
"The architect recommended $180,000 worth of improvements."
Or:
"The architect recommended $180,000’s worth of improvements."
My inclination is toward the second, because the phrase is possessive. But… dagnabit, it looks wrong. It makes me feel like someone who incorrectly thinks an apostrophe is needed when talking about dates (“I went to college in the mid-1990’s” – ugh!).
Maybe I’ve just been proofing too many numbers today and nothing looks right anymore. Can someone who isn’t burned out please confirm my instincts (or tell me I’m wrong, perish the thought)?
