Teresa's estimate for the height of the giraffe is 18 feet, but the actual height is 16 feet. We need to calculate the percent error, which is a measure of how much Teresa's estimate differs from the actual value.
To do this, we first need to find the difference between the estimate and the actual value: 18 feet - 16 feet = 2 feet.
Next, we calculate the percent error by dividing the difference by the actual value and multiplying by 100: (2 feet / 16 feet) * 100 = 12.5%.
Therefore, Teresa's percent error is 12.5%.
