Do you use the same method to find the percent of decrease as to find a percent of increase?

Yes, the methods for finding both percent of decrease and percent of increase are similar. For both, you calculate the difference between the original value and the new value, then divide that difference by the original value. However, for percent of increase, you use the formula ((\text{New Value} - \text{Original Value}) / \text{Original Value} \times 100%), while for percent of decrease, you use ((\text{Original Value} - \text{New Value}) / \text{Original Value} \times 100%). The key difference lies in the direction of the change.

How do you know if a percent is a decrease or increase?

To determine if a percent represents a decrease or an increase, compare the original value to the new value. If the new value is greater than the original, it indicates a percentage increase. Conversely, if the new value is less than the original, it signifies a percentage decrease. You can also calculate the percent change using the formula: ((\text{New Value} - \text{Original Value}) / \text{Original Value} \times 100), where a positive result indicates an increase and a negative result indicates a decrease.
