Darla spent $120.37 on groceries in january, $108.45 in february, and $114.86 in march. what was the average monthly cost of darla’s groceries?

The average of her grocery shopping is $114.56. How you get the average is you add all of the numbers together and divide by how many numbers there are. And in this case, there were 3 numbers. Hope this helps! :)

$114.56 i am inferring... if i am correct, you add the totals together and divide by 3.Hopefully i helped

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
