Given that 150 is increased to 861
The absolute change formula is
[tex]\text{Absolute Change}=New\text{ value - Old value}[/tex]
Where
The new value = 861
The old value = 150
The absolute change is
[tex]\text{Absolute Change}=861-150=711[/tex]
Hence, the absolute change is 711
The formula for percentage is
[tex]Percentage\text{ change}=\frac{New\text{ value-Old value}}{Old\text{ value}}\times100\text{\%}[/tex]
Substitute the values into the percentage change formula
[tex]\begin{gathered} Percentage\text{ change}=\frac{New\text{ value-Old value}}{Old\text{ value}}\times100\text{\%} \\ Percentage\text{ change}=\frac{861-150}{150}\times100\text{\%} \\ Percentage\text{ change}=\frac{711}{150}\times100\text{\%}=4.74\times100\times=474\text{\%} \\ Percentage\text{ change}=474\text{\%} \end{gathered}[/tex]
Hence, the percentage change is 474% increase
