Question

is the percent increase from 50 to 80 same as the percent decrease from 80 to 50 ​

Answer 1

DETAILED ANSWER:

A change from 80 to 50 represents a negative change (decrease) of -37.5%

Use the formula found below on this webpage to find the percent change by replacing the given values:

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

Percent change = [(50 - 80) / |80|] x 100 = [(-30) / 80] x 100 = -37.5 % (decrease)

Hope it helps....

Answer 2

$percentage = \frac{new \: - \: old \: }{old} \times 100$

For 50 to 80

$\% = \frac{80 - 50}{50} \times 100 \\ \\ \% = 60\%$

For 80 to 50

$\% = \frac{50 - 80}{80} \times 100 \\ \\ \% = - 37.5\%$
