Respuesta :
If I think I’m understanding it, the new members out of the 200 original would be adding 28% to the mix
the percentage increase of members at the skating club is 28%
What is relative change?
"relative change = (final value - initial value)/ initial value"
What is percent change?
percent change = relative change × 100
For given example,
There were 200 members at a skating club. After some new members went in, there were 256 members altogether at the skating club.
initial value (a) = 200
final value (b) = 256
So, relative increase is,
⇒ R = (b - a)/a
⇒ R = (256 - 200)/200
⇒ R = 56/200
⇒ R = 0.28
So, the percent increase is,
⇒ P = R × 100
⇒ P = 0.28 × 100
⇒ P = 28%
Therefore, the percentage increase of members at the skating club is 28%
