Final answer:
The percent of change when the original value decreases from 25 to 18 is a 28% decrease.
Step-by-step explanation:
The percent of change from an original value of 25 to a new value of 18 is calculated using the formula Percentage change = [(New Value − Original Value) / Original Value] × 100 In this case Determine the change in value: 18 − 25 = −7.Divide the change by the original value: −7 / 25 = −0.28.Convert to a percent: −0.28 × 100 = −28%.The negative sign indicates a decrease in value. Therefore, the percentage decrease is 28%.
