The relative error is calculated as the absolute error divided by the true value, then multiplied by 100 to get a percentage. Here, the absolute error is $0.25 ($2.75 - $2.50), and the true value is $2.75. So, the relative error is ($0.25 / $2.75) * 100 = 9.09%, which rounds to -9.1% when considering the error was an underestimation.
