Answer: The industry's approximate four-firm concentration ratio is 61%

Explanation:

Hi, to answer this question, first we have to sum all the four firms sales:

Mathematically speaking:

35 + 17 + 6.8 + 2.2 = 61 billion

Now, we have to divide the result by the total industrial sales:

61 billion / 100 billion = 0.61

To express it as a percentage we have to multiply it by 100

0.61 x 100 = 61%

The industry's approximate four-firm concentration ratio is 61%
