Answer: D. $10 Billion
Step-by-step explanation:
The United States has a large economy with a very large number of cars which was estimated to be around 280 million in the last quarter of 2019. With these many cars it would be improbable that there would not be quite a number of accidents and there are. In the year 2018, around 12 million cars were involved in motor accidents.
With such a staggeringly high number of cars involved in collisions, it is no wonder that it is estimated that the collision repair industry does around $10 billion worth of business every year.
