Answer: C. 11%
Step-by-step explanation: To find the percent increase, we can use the formula:
Percent Increase = ((New Value - Old Value) / Old Value) * 100
Plugging in the given values:
Percent Increase = ((111,000 - 100,000) / 100,000) * 100
Simplifying the equation:
Percent Increase = (11,000 / 100,000) * 100
Calculating the percentage:
Percent Increase = 11%
Therefore, the correct answer is C. 11%.
