percent of change
20 is decreased to 11. What is the percent of change?
11 = x(20)
x = .55
1 - .55 = .45
so 45 % decrease
20 is decreased to 11
To find the percent of change, we first need to know the original value and the new value. In this case, the original value is 20 and the new value is 11.
To calculate the percent of change, use the following formula:
Percent of Change = ((New Value - Original Value) / Original Value) * 100
Applying this formula to the given values:
Percent of Change = ((11 - 20) / 20) * 100
Now, let's calculate it step by step:
Step 1: 11 - 20 = -9
Step 2: -9 / 20 = -0.45 (decimal)
Step 3: -0.45 * 100 = -45
The percent of change is -45%.
Note that the negative sign indicates a decrease. In this case, there was a 45% decrease from the original value of 20 to the new value of 11.
