[AI-generated answer — Bot GPT 3.5]

To find the percent error, we need to compare the difference between Teresa's estimate and the actual height to the actual height.

Actual height = 16 feet
Teresa's estimate = 18 feet

Difference = Actual height - Teresa's estimate = 16 - 18 = -2 feet

Next, we will find the percent error using the formula:

Percent Error = (Difference / Actual height) * 100

Percent Error = (-2 / 16) * 100 = -12.5

Since percent error is always positive, we will take the absolute value of -12.5 to get 12.5.

Therefore, Teresa's percent error is 12.5%.
