A company finds 8 bags with faulty zippers in a sample of 500. Predict how many bags with faulty zippers there are in a shipment of 20,000.
A. 320
B. 360
C. 400

Respuesta :

To answer this problem you have to use a ratio, if it begins with 8:500, multiply 40 or 20,000/500 on both sides to get 320:20,000
B because it is division and you have to divide 20000 by 4000
