Question: The total yearly food bill for a family of four is $8589.88. To the nearest cent, what is the mean weekly food bill?

Would I take $8589.88 divided by 52.365 (this is the number of weeks in a year) to get the answer $164.04?

It is generally accepted that there are 52 weeks in a year, so I would divide by 52

that comes out to 165.19

(curious how you got 52.365 weeks in a year

365/7 = 52.14286

366/7 = 52.2857 (for a leap year) )

After I posted that, I realized that I should have put down 52 (rounded). I actually got the total number of weeks in a year, by the interent. It had this number, but also the 52.365. Not sure how they did that.

Thanks
