Teresa thinks the giraffe is 18 feet tall, but it is actually 16 feet tall. To find the percent error, we need to see how much Teresa's estimate differs from the actual height.
First, we find the difference between the estimated height and the actual height: 18 feet - 16 feet = 2 feet.
Next, we need to find what percent the difference is of the actual height. To do this, we divide the difference by the actual height and then multiply by 100: (2 feet / 16 feet) * 100 = 12.5%.
So, Teresa's percent error is 12.5%.
reword but make it sound like 12 year old
