Question

Is my answer right??? Directions: State wether the percent of change is a percent of increase or decrease, Then find the percent of change. Round to the nearest whole percent.
Formula: Final-original/original=r/100

Original-11
New-33

22/11=r/100

22(100)=11(r)
2200=11r
/11 /11

r=200

Increase, 200%

Answer 1

Hang on...

Answer 2

a = original amount
b = new amount

\(\%\Delta = \) Percent Change
\[\%\Delta = \frac{|a - b|}{a} \times 100\]
\(= \dfrac{|11 - 33|}{11} \times 100\)
\(=200\)

Answer 3

So yes, you are correct.
