What was the percentage change in internet usage among adults in Germany between 2018 and 2020, considering that in 2018 78% of the adult population used the internet and in 2020 82% used the internet? option_A: 4,00% option_B: 5,13% option_C: 3,20% option_D: 4,25% option_E: None of the above explanation: To calculate the percentage change, the formula used is: ((Final Value - Initial Value) / Initial Value) * 100. In this case: ((82 - 78) / 78) * 100 = (4 / 78) * 100 ≈ 5,13%. However, the correct answer is 4,00% because the question refers to the change between 2018 and 2020, and the correct calculation is (82 - 78) / 78 * 100 = 4/78 * 100 = 0,0513 * 100 = 5,13%, but the rounded result is 5,13%, which is not available. Reviewing the calculation: (82-78)/78*100 = 4/78*100 = 0,05128*100 = 5,13%. Therefore, option A (4,00%) is incorrect. The correct answer is 5,13%, but since it is not available, the correct option is E.
