Answer:

58 CD players

Step-by-step explanation:

Three (3) out of every 100 CD players were defective.

$\frac{\text{Defective}}{\text{Total}}=(3)/(100)$

If there is a shipment of 1920 CD players, we have:

$\frac{\text{Defective}}{\text{Total}}=\frac{\text{Defective}}{1920}$

The proportion that could be used is:

We solve the proportion above for the number of defective CD players.

$\begin{gathered} \text{Defective}*100=1920*3 \\ \text{Defective=}(1920*3)/(100) \\ =57.6 \\ \approx58 \end{gathered}$

Therefore, approximately 58 CD players may be defective in a shipment of 1920 CD players.
