A copyeditor is working for a publisher that has its own house style guide. The house guide dictates that all numbers from one to fifty should be spelled out. However, the author has followed The Chicago Manual of Style's general rule, spelling out numbers zero through one hundred. In a sentence that reads, 'The study included 54 participants,' what is the copyeditor's most appropriate action?
-
A
Change '54' to 'fifty-four' to match the house style guide.
-
B
Leave '54' as is, because it is over the house style's threshold of fifty.
-
C
Query the author about their preference for number styling.
-
D
Change '54' to 'fifty-four' and make a note to follow Chicago style for all other numbers.
