The calculated value that Erika spend on school supplies this year is $115.

Actual value that she spent is $82.50.

We need to find Erika's percent of error. Percentage error is given by the formula as follows :

$\%=\dfrac{\text{calculated value}-\text{actual value}}{\text{actual value}}\times 100\\\\\%=\dfrac{115-82.5}{82.5}\times 100\\\\\%=39.39\%$

So, Erika's percent of error is 39.39%.
