Question

You estimate that a small restaurant will serve 430 customers the first week it is open. The actual number of customers the first week is 400. Find the percent error

Answer 1

7.5 %

Explanation:

Given:

You estimate that a small restaurant will serve 430 customers the first week ,this is our experimental value.

The actual number of customers the first week is 400, this is the theoretical value.

To find:

Find the percent error ?

Solution:

As we know that:

`Percent \ error = (experimental \ value - theoretical \ value)/(theoretical \ value) *100`

`=(430-400)/(400) *100\\=(30)/(400) *100\\=(3000)/(400) =7.5\%`

Therefore, percent error is 7.5 % for estimation of coming of the customers in the first week.
