Amaretta's birthday is July 27, and her brother Enzo's birthday is September 3. Every year, Amaretta and Enzo celebrate by eating cake every day from Amaretta's birthday through Enzo's birthday (including both birthdays). If they did this for the first time in 2008, how many cake-eating days will they have observed by the end of 2016?
5 days in july 31 days is august 3 days in septemeber 39 days of cake eating per year 9 years from 2008 to 2016. Assuming they aren't dead from all the cake or have diabetes, then 39*9=351 days of eating cake.
Does this make sense?
This is correct. The point of the problem is to avoid a fencepost error by counting both ends of the spans.
