Answer:
The percent of change is 44.7%
Step-by-step explanation:
Given that:
38 staples to 55 staples
As the number of staples are increased, therefore, the percent will also increase.
Difference = 55 - 38 = 17 staples
Percent of change = ![\frac{Difference}{Original\ number}*100](https://tex.z-dn.net/?f=%5Cfrac%7BDifference%7D%7BOriginal%5C%20number%7D%2A100)
Percent of change = ![\frac{17}{38}*100](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B38%7D%2A100)
Percent of change = 0.447*100
Percent of change = 44.7%
Hence,
The percent of change is 44.7%
