Answer :
We have a variable that goes from a state of value 24 to a value of 6, so we have a decrease.
We can calculate the percentage change with the following formula:
[tex]\begin{gathered} x_1=24 \\ x_2=6 \\ \Delta=\frac{x_2-x_1}{x_1}\cdot100\%=\frac{6-24}{24}\cdot100\%=\frac{-18}{24}\cdot100\%=-0.75\cdot100\%=-75\% \end{gathered}[/tex]The variable value decrease by 75% (or a change of -75%).
Answer: % of change is Decrease was 75%.
