Write with (AP) style

Is this correct, under AP Style rules?

70% of couples who live together . . .

No. This is under the "numerals" heading:

Spell out a numeral at the beginning of a sentence.

Plus, if you look under "percent," you find examples that show you should use the word, not the figure.

Also, many of you referred to Mayor Datoli as Mayor Datoli. Is that okay under AP style rules? No. This is what it says under "names":

In general, use last names only on second reference.

So you should have included a first name. Did you have one given to you? No. So, what should you have then done?

This is a trick question that you'll constantly be facing this semester. What's the correct answer?

Start checking/familiarizing yourself with AP Style, folks!
