Answer:
The percent of change is <u>20%</u>.
And it is increased by last month.
Step-by-step explanation:
Given:
The ice cream parlor has 30 flavors, but for the last week they have only had 25 flavors.
Now, to find the percent of change.
Flavors ice cream parlor has = 30.
Flavors last week they had = 25.
So, the flavors increased from last week by:
![30-25=5\ flavors.](https://tex.z-dn.net/?f=30-25%3D5%5C%20flavors.)
Now, to get the percent of change:
![\frac{5}{25} \times 100](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B25%7D%20%5Ctimes%20100)
![=\frac{500}{25}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B500%7D%7B25%7D)
![=20\%.](https://tex.z-dn.net/?f=%3D20%5C%25.)
<em>Thus, the percent of change is 20%.</em>
<em>The flavor is increased by last month.</em>
Therefore, the percent of change is 20%.
And it is increased by last month.
