Question

A warehouse worker fills 150 orders per day on average. From day to day, the number of orders varies by 2%. What is the range of the number of orders the worker fills each day?

Answer 1

The range is from 147 to 153 orders per day

Explanation:

orders varies by 2% means that orders can be LOWER THAN THE AVERAGE, or HIGHER THAN THE AVERAGE.

That is, by 2%.

First, we need to find the decimal of 2%, so

2/100 = 0.02

We multiply this with the average number of order, 150, to get the varying amount:

0.02 * 150 = 3

Thus, the range would be:

150 - 3 = 147

150 + 3 = 153

The range is from 147 to 153 orders per day
