To find the manager's percent error, we'll use the following formula:
Percent Error = (|Estimated Value - Actual Value| / Actual Value) * 100
Given that the estimated value is 325 and the actual value is 297, we can substitute these values into the formula:
Percent Error = (|325 - 297| / 297) * 100
Simplifying the numerator:
Percent Error = (28 / 297) * 100
Calculating the division:
Percent Error = 0.0946 * 100
Percent Error ≈ 9.46%
Therefore, the manager's percent error in estimating the number of jars of spaghetti sauce sold last week is approximately 9.46%.
To find the manager's percent error, we need to compare the estimated value (325 jars) to the actual value (297 jars) and calculate the percentage difference.
First, we need to find the absolute difference between the estimated and actual values:
Absolute difference = |Estimated value - Actual value|
Absolute difference = |325 - 297|
Absolute difference = |28|
Next, we calculate the percent error using the formula:
Percent error = (Absolute difference / Actual value) * 100
Percent error = (28 / 297) * 100
After calculating this expression, we find that the manager's percent error is approximately 9.43%.
