Q. What is the percent of change from 4040 to 4444?\newlineChoices:\newline(A) 10%10\% decrease\newline(B) 15%15\% decrease\newline(C) 10%10\% increase\newline(D) 15%15\% increase
  1. Calculate Difference: Step 11: Calculate the difference between the final value and the initial value.\newlineInitial value: 4040\newlineFinal value: 4444\newlineDifference = Final value - Initial value = 4440=444 - 40 = 4
  2. Calculate Percent Change: Step 22: Calculate the percent of change.\newlineOriginal amount: 4040\newlineAmount of change: 44\newlinePercent of change = (Amount of change/Original amount)×100%(\text{Amount of change} / \text{Original amount}) \times 100\%\newlinePercent of change = (4/40)×100%=0.1×100%=10%(4 / 40) \times 100\% = 0.1 \times 100\% = 10\%
  3. Determine Increase or Decrease: Step 33: Determine if it's an increase or decrease. Since the number goes up from 4040 to 4444, it is an increase.
