percentage increase

Answer 2

Answer:

250%

Step-by-step explanation:

Where: 80 is the old value and 280 is the new value.

Percent change = [(New - Old ) / |Old|] x 100%

Percent change = [(280 - 80) / |80|] x 100 = [(200) / 80] x 100 = 250 % (decrease)

In this case we have a positive change (increase) of 250 percent because the new value is smaller than the old value.
