Solution

To calculate the percent error, you first need to find the difference between the estimated value and the actual value. In this case, the estimated value is 340 and the actual value is 260.

Step 1: Subtract the actual value from the estimated value: 340 - 260 = 80

Step 2: Divide the difference by the actual value: 80 / 260 = 0.3077

Step 3: Multiply the result by 100 to get the percent error: 0.3077 * 100 = 30.77%

Step 4: Round to the nearest percent: The percent error is approximately 31%.
