Photography club would like to raise money for a local health organization by selling popcorn the club predicts they need to sell 250 bags of popcorn to reach their goal at the end of the fundraiser. They 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 can be calculated using the following formula:
Percent Error = [(|Measured Value - Actual Value|) / Actual Value] x 100
In this case, the measured value is 266 bags and the actual value (goal) is 250 bags.
Percent Error = [(|266 - 250|) / 250] x 100
Percent Error = (16 / 250) x 100
Percent Error = 0.064 x 100
Percent Error = 6.4%
Rounding the answer to the nearest whole number, the percent error is 6%.
