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.
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?
Show your work and I'll tell you what is wrong with your factors.
To find out how many doughnuts Fannie eats in a week, we'll start by figuring out how many doughnuts she eats in one day.
Since she eats a dozen doughnuts every 36 hours, we can convert this to 24 hours, which is a standard day.
Step 1: Set up a proportion:
12 doughnuts / 36 hours = x doughnuts / 24 hours
Step 2: Cross-multiply and solve for x:
12 * 24 = 36 * x
288 = 36x
Step 3: Divide both sides by 36:
(288 / 36) = x
8 = x
So Fannie eats 8 doughnuts in one day.
Now, let's calculate how many doughnuts she eats in a week. There are 7 days in a week, so we'll multiply the number of doughnuts she eats in one day by 7:
8 doughnuts/day * 7 days/week = 56 doughnuts/week
Therefore, Fannie eats 56 doughnuts in a week.
