Question

Find the percent of change.
From 25 teachers to 30 teachers.

Answer 1

To calculate the percent change of two numbers, such as 25 to 30, you use the Percent Change Formula, where a is the start value and b is the end value.

(b - a)/a × 100

When we insert a = 25 and b = 30 in the formula above, then we get the following that we can simplify and solve to get the percent change from 25 to 30.

(30 - 25)/25 × 100

5/25 × 100

Change = 20%
