Christians estimates that she will spend $250 on new summer clothes.She actually spent $350. What is the percent error?Round to the nearest whole percent

Verified Answer :

The percent error is 40%, given that $250 is the accepted value, which I think it is. 

The equation to solve for percent error is (|accepted value - experimental value|)/accepted value100= percent error

Substitute numbers, and you get ( |250-350| )/250
100=40%
