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

To find the mean weekly food bill, you need to divide the total yearly food bill by the number of weeks in a year.

You correctly identified that there are approximately 52.365 weeks in a year. However, when calculating the mean, it is common practice to round to a whole number rather than decimal places. Therefore, you should round the number of weeks to 52.

So, the calculation would be:

$8589.88 / 52 = $165.57

Rounding this to the nearest cent, as asked in the question, the mean weekly food bill for the family of four would be $165.57.
