Full solution

Q. What is the percent of change from 2020 to 3030?\newlineChoices:\newline(A) 10%10\% increase\newline(B) 50%50\% decrease\newline(C) 50%50\% increase\newline(D) 10%10\% decrease
  1. Calculate Difference: Calculate the difference between the final value and the initial value.\newlineDifference = 3020=1030 - 20 = 10.
  2. Determine Original Amount: Determine the original amount for calculating the percent change. Original amount = 2020.
  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 = (10/20)×100%(10 / 20) \times 100\% = 5050\%.
  4. Identify Increase or Decrease: Identify whether it is an increase or a decrease.\newlineSince the value increased from 2020 to 3030, it is an increase.
