To find the percent error, we need to compare the estimated height to the actual height using the formula:
Percent Error = (|Estimated Value - Actual Value| / Actual Value) * 100
Substituting the given values:
Percent Error = (|18 - 16| / 16) * 100
= (2 / 16) * 100
= 0.125 * 100
= 12.5
Therefore, Teresa's percent error is 12.5%.
