To find the percentage decline using the initial value approach, we need to find the difference between the initial value and the final value, and then divide it by the initial value and multiply by 100. In this case, the initial value is 100 and the final value is 60. So the difference is 100 - 60 = 40. Then, dividing by the initial value and multiplying by 100 gives (40/100) x 100 = 40 percent. Therefore, the correct answer is C) 40 percent.
