Q. What is the percent of change from 55 to 66?\newlineChoices:\newline(A) 20%20\% decrease\newline(B) 22%22\% increase\newline(C) 20%20\% increase\newline(D) 22%22\% decrease
  1. Calculate Difference: Calculate the difference between the final and initial values.\newlineDifference = 65=16 - 5 = 1
  2. Determine Original Amount: Determine the original amount for calculating the percent change. Original amount = 55
  3. Calculate Percent of Change: Calculate the percent of change using the formula: (Amount of change/Original amount)×100%(\text{Amount of change} / \text{Original amount}) \times 100\%.\newlinePercent of change = (1/5)×100%=20%(1 / 5) \times 100\% = 20\%
  4. Identify Increase or Decrease: Identify whether it is an increase or a decrease.\newlineSince the value increased from 55 to 66, it is an increase.
