What is the percent of change from 2 to 1? Choices: (A)1% increase (B)50% decrease (C)50% increase (D)1% decrease

Calculate Difference: Calculate the difference between the final and initial values. Initial value: 2 Final value: 1 Difference = Final value - Initial value = 1 - 2 = -1Calculate Percent Change: Calculate the percent of change using the formula. Percent of change = (Difference / Initial value) × 100% Percent of change = (-1 / 2) × 100% = -50%Determine Increase or Decrease: Determine if it's an increase or decrease.

Calculate Difference: Calculate the difference between the final and initial values. $\newline$ Initial value: $2$ $\newline$ Final value: $1$ $\newline$ Difference = Final value - Initial value = $1 - 2 = -1$
Calculate Percent Change: Calculate the percent of change using the formula. $\newline$ Percent of change = $(\frac{\text{Difference}}{\text{Initial value}}) \times 100\%$ $\newline$ Percent of change = $(\frac{-1}{2}) \times 100\%$ = $-50$ \%
Determine Increase or Decrease: Determine if it's an increase or decrease. $\newline$ Since the percent change is negative, it indicates a decrease.
