192
Step-by-step explanation:
To find how many phones are expected to be defective, we need to represent the values in a fraction.

x = number of defective phones

To get the value of x we need to multiply both sides by 8000 to leave x alone.



So around 192 cell phones are expected to be defective out of 8000 phones.
