Danielle estimates that she well spend $250 on new summwe colthes. She acually spent $350. What is the percent error? Round to the nearest whole percent.

The percent error is 40%

Step-by-step explanation:

To calculate the error percentage we have to divide the final amount over the initial amount

350 / 250 = 1.4

then we subtract 1 since this represents the estimated value

1.4 - 1 = 0.4

this is the error factor we have, to express it as a percentage we simply multiply by 100

0.4 * 100 = 40%

The percent error is 40%
