Answer: There is change of 20% in the depth of snow from yesterday to today.
Step-by-step explanation:
Since we have given that
Quantity of snow on yesterday in front of Archie's house = 2 feet
Quantity of snow on today in front of Archie's house = 1.6 feet
We need to find the percent change in the depth of the snow.
Firstly, difference between yesterday and today is given by
1.6-2=-0.4
So, Percentage change in the depth of the snow is given by
![\dfrac{Difference}{Original}\times 100\\\\=\dfrac{-0.4}{2}\times 100\\\\=-20\%](https://tex.z-dn.net/?f=%5Cdfrac%7BDifference%7D%7BOriginal%7D%5Ctimes%20100%5C%5C%5C%5C%3D%5Cdfrac%7B-0.4%7D%7B2%7D%5Ctimes%20100%5C%5C%5C%5C%3D-20%5C%25)
Hence, there is change of 20% in the depth of snow from yesterday to today.
