Calculate Difference: Calculate the difference between the initial and final values. $\newline$ Initial value: $10$ $\newline$ Final value: $1$ $\newline$ Difference = Final value - Initial value = $1 - 10 = -9$
Calculate Percent Change: Calculate the percent of change using the formula. $\newline$ Percent of change = $(\text{Difference} / \text{Initial value}) \times 100\%$ $\newline$ Percent of change = $(-9 / 10) \times 100\%$ = $-90\%$
