Answer:
20%
Step-by-step explanation:
Step 1: Subtract starting value minus the final value (decrease)
Step 2: Divide the decrease by the original number
Step 3: Multiply the result by 100 to get a percent decrease

Therefore, the percent decrease of the price of paper per package is 20%
<em>Note: If the percentage is negative, it means there was an increase and not a decrease.</em>
