Answer: 25% Change
Step-by-step explanation: To find the percent change from 84 to 63, we will be using the "percent change" equation.
change = percent change x actual
To find the change subtract 63 from 84. 84 - 63 = 21. So the change is 21.
21 = percent change x actual
The actual is 84, because 84 is your original amount.
21 = percent change x 84 (Solve for p, percent change.)
21 = p x 84
21/84 = p
0.25 = p
Now, multiply the decimal 0.25 by 100 to get the percent change.
0.25 x 100 = 25, Or a 25% change.
