The price is down ten percent.
1. The price is already down 10%.
2. The first two hours are down 10%.
1 is a definitely correct sentence. What I'm wondering is why the subject can be 'hours' in 2. I don't get it at all, but it is used in a movie. The meaning should be "the sales volume for the first two hours is down 10%." Is it possible to say like that? Without a proper subject?
Thank you so much!
