A photography club would like to raise money for a local health organization by selling popcorn. The club predicts that they need to sell 250 bags of popcorn to reach their goal. At the end of the fundraiser, the sold 266 bags of popcorn and met their goal. What is the percent error? Round the answer to the nearest whole number.
The percent error is calculated by finding the difference between the predicted and actual values, dividing that difference by the predicted value, and then multiplying by 100.
The predicted value is 250 bags of popcorn and the actual value is 266 bags of popcorn.
The difference is 266 - 250 = 16 bags of popcorn.
The percent error is (16 / 250) * 100 = 6.4%.
Rounding to the nearest whole number, the percent error is 6%. Answer: \boxed{6}.
