Teresa estimated that a giraffe in a zoo is 18 feet tall, but it is actually 16 feet tall. To find the percent error, we need to find the difference between Teresa's estimate and the actual height of the giraffe, which is 2 feet. Then, we divide this difference by the actual height and multiply by 100 to find the percent. The percent error is 12.5%.
