she estimated that she would spend $175.
she actually spent $97.5


she was off by 175 - 97.5 = 77.5


the percent error that her estimate was from the actual value would be:


77.5 / 97.5 * 100 = 79.48717949 percent more than the actual value.


the percent error that her actual value was from the estimate would be:


77.5 / 175 * 100 = 44.28571429 percent less than the estimate.


i believe you are looking for the percent error over the actual value.


that would be 79.48717949 percent.
