Question

You estimate that 430 customers will be served at a small restaurant. 400 is the actual number of customers. What is the percent error? Round answer to the whole percent.

Answer 1

To calculate the percent error, subtract the actual number from the estimated number, divide by the actual number, multiply by 100, and round to the nearest whole percent. In this case, the percent error is 8%.

Step-by-step explanation:

To calculate the percent error, we first need to find the absolute value of the difference between the estimated number of customers and the actual number of customers. Then, we divide that difference by the actual value and multiply by 100 to get the percent error.

Step-by-Step Calculation:

1. Find the absolute error: |estimated – actual| = |430 – 400| = 30.
2. Divide the absolute error by the actual number of customers: 30 / 400 = 0.075.
3. Multiply by 100 to get the percentage: 0.075 × 100 = 7.5%.
4. Round the percentage to the nearest whole number: 7.5% rounds to 8%.

Therefore, the percent error in the estimate is 8%.
