A Correct answer
Explanation

Percentage increase = ((New Value - Old Value) / Old Value) * 100. (1100 - 1000) / 1000 = 100 / 1000 = 0.1, which is 10%.

AI explanation

Using the percentage increase formula, ((Final Value - Initial Value) / Initial Value) * 100, calculate the change from 1000 to 1100. Substitute the values to get ((1100 - 1000) / 1000) * 100, resulting in (100 / 1000) * 100 = 10%. The percentage increase is 10%.
