Final answer:
To find the percent of increase, subtract the original value from the new value, divide by the original value, and multiply by 100.
Step-by-step explanation:
To find the percent of increase, we need to find the difference between the new value and the original value, then divide that difference by the original value and multiply by 100.
Step 1: Find the difference: 27.5 - 25 = 2.5
Step 2: Divide the difference by the original value: 2.5 / 25 = 0.1
Step 3: Multiply by 100 to get the percent: 0.1 x 100 = 10%
The percent of increase is 10%.
