Question

A store offers four different brands of a product. It decides toeliminate one brand based on the likelihood a customer willreturn that brand. The table shows the number of items ofeach brand that were returned over the past year and the totalsold.

Answer 1

Solution

- The way to find the Brand that gets returned the most, we find the proportion of the brands returned.

- The way we find the proportion is using the formula below:

$\frac{Returns}{Total\text{ }sold}$

- Thus, we have:

$\begin{gathered} Brand\text{ }A: \\ \frac{28}{594}=0.047138047138... \\ \\ \\ Brand\text{ }B: \\ \frac{15}{426}=0.035211267606... \\ \\ \\ Brand\text{ }C: \\ \frac{27}{664}=0.040662650602... \\ \\ \\ Brand\text{ }D: \\ \frac{25}{313}=0.079872204473... \end{gathered}$

- Since Brand D has the highest proportion, it means that Brand D has the highest return proportion.

- Thus, Brand D should be eliminated
