I have been getting quite a few questions on this lately, so just so we are clear, here is the AP Style rule for numbers:
Spell out numbers 1-9, numerals are used for 10 and above. Ages, addresses and phone numbers are always numerals. For money figures, always use the dollar sign. Ex. $33.7 million, and do not spell out ‘dollars.’
Here is the AP Style rule for collective nouns:
“Collective nouns,” appear as plurals, ‘team,’ ‘family,’ ‘company’ among them, but should be treated as a singular noun.
Incorrect: ‘The band is releasing their new CD.”
Correct: “The band is releasing its new CD.”
