It is a proportion. 200 over 3 equals 10,000 over x. From the 200 side. multiply everything by 50 (200x50=10,000) and you get 150 cars that are defective.

Answer:

There will be 150 defective cars among the set of 10,000 cars

Step-by-step explanation:

For every 200 cars 3 are defective

Let X numbers of car be defective out of 10000 cars

There is a proportional relationship between the two

Thus,

[tex]\frac{3}{200} = \frac{X}{10,000} \\X = \frac{(10,000)(3)}{(200)} = 50 * 3\\= 150[/tex]
