How do you solve percent of change?
My problem says identify the percent of change as an increase or decrease. Find the percent change. Round to the nearest 10th.
20 to 25
25 - 20 = 5
5/20 = 0.25 = 25% increase
Find the percent change from $20 to $25
To solve for percent of change, you follow these steps:
1. Subtract the initial value from the final value.
In this case, you would subtract 20 from 25: 25 - 20 = 5.
2. Divide the difference by the initial value.
Divide 5 by 20: 5 / 20 = 0.25.
3. Multiply the result by 100.
Multiply 0.25 by 100: 0.25 * 100 = 25.
The percent change is 25%. Since the question asks you to round to the nearest 10th, round 25 to the nearest 10th: 25.0.
Therefore, the percent of change as an increase from 20 to 25 is 25.0%.
