Fannie eats a dozen doughnuts every 36 hours. How many doughnut does she eat in a week? I used Dimensional Analysis(which isn't helping at all), but it keeps giving me weird number, like 36 over 2016 or 252 over 2016.

Answer 1

How many hours in a week.
(24 hrs/day) x (7 days/week) = 168 hrs/week.
So (12 donu/36 hrs) x (168 hrs/week) = ?
56 doughnuts/week?
