Answer:

We can expect 28 defected cars.

Step-by-step explanation:

Let us assume that the defected cars are "uniformly distributed" in the total set of cars.

Then we can write the proportion 8%2F360 = x%2F1260 for the unknown amount x of defected cars among 1260 cars.

Solving the proportion for x you get

x = 8%2A1260%2F360 = 8%2A3.5 = 28.
