You can put this solution on YOUR website!
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.
