Answer 1

Percentage error can be calculated using the formula:

Percentage Error = (Estimated Value - Actual Value) / Actual Value * 100

Using this formula, we can substitute the values into the formula:

Percentage Error = (18 - 16) / 16 * 100

Simplifying the expression:

Percentage Error = 2 / 16 * 100

Percentage Error = 0.125 * 100

Percentage Error = 12.5%

Therefore, Teresa’s percentage error is 12.5%.
