Answer: 80
-----------------------------------------
Explanation:
x = number of defective drives in the shipment of 20,000 total
We are told that 2 defective drives are in the shipment of 500. So the first fraction to set up is 2/500
The second fraction is x/20000 as we divide in the same order as before (number of defective over the total)
Set those two fractions together to get this proportion
2/500 = x/20000
Now cross multiply
2/500 = x/20000
2*20000 = 500*x
40000 = 500*x
500x = 40000
The last step is to divide both sides by 500 to isolate x
500x = 40000
500x/500 = 40000/500
x = 80 which is the answer we want
Note: This is an expected/estimated amount and not entirely guaranteed to be reality. It's based on the previous ratio of 2/500, assuming the same ratio is held in check.
