Without rephrasing it… I determined that Ann is 16.

I'm not sure why it needs rephrasing—it seems pretty straightforward? What am I missing?

16 works (as another pointed out). Ann is 16 and Mary would have been that age 8 years ago—when of course Ann would then have been 8 (Mary, at 16, was twice her age).

> (Mary, at 16, was twice her age)

The problem states “She _is_ twice as old as Ann was”, not “She _was_ twice as old as Ann was”.
