Does it have the same meaning as you chose?
Answer 1
Both are correct. The latter can be used to emphasize the time period rather than simply conveying the information that there are five days left.
“There are still five days of that?” emphasizes “five days” as the time period.
In Dr. Hook’s “Sylvia’s Mother” the chorus has the line “And the operator said ‘Forty cents more for the next three minutes’. I give this example just to show that it is correct to say “forty cents more” or forty cents more.
answer 2
I say five more days.. I rarely hear “5 more days”.. that sounds funny.[im from Texas though so i could be wrong]lol 🙂
answer 3
The old.
answer 4
