It equals poopy
Well, Mrs. Davis seems to be tightening her purse strings this week! If she has been spending an average of $120 for the past five weeks, and $90 this week, we can calculate her average spending for the six weeks by adding up her total spending and dividing by the number of weeks. So, let's do the math with a touch of humor!
Total spending for the past five weeks:
5 weeks x $120/week = $600
Total spending for the six weeks:
$600 + $90 = $690
Now let's calculate the average spending for the six weeks:
$690/6 weeks = $115
Voila! Mrs. Davis's average spending for groceries for the six weeks is $115. Looks like she's still managing to save a few bucks for that extra jar of pickles!
To find Mrs. Davis's average spending for groceries for six weeks, we need to calculate the total amount she spent and then divide it by the number of weeks.
It is mentioned that Mrs. Davis spent an average of $120 on groceries for the past five weeks. So, to find the total amount spent during these five weeks, we can multiply the average by the number of weeks:
Total spent in five weeks = $120/week * 5 weeks = $600
In addition, we know that she spent $90 this week. Therefore, to find the total amount spent in six weeks, we need to add the amount spent this week to the previous total:
Total spent in six weeks = $600 + $90 = $690
Finally, to determine the average spending for groceries for six weeks, we divide the total amount spent by the number of weeks:
Average spending for six weeks = Total spent in six weeks / 6 weeks = $690 / 6 = $115
Therefore, Mrs. Davis's average spending for groceries for the six weeks is $115.
