ANSWER:

2nd option: 0 ≤ x < 5.6 and 24.13 < x ≤ 32.82

Explanation:

We need to determine the range of values of x for costs to be less than $175,000.

In points 5.6 and 24.13, the cost is exactly $175,000, which means that the solution interval cannot include these values.

So the correct answer is:

2nd option: 0 ≤ x < 5.6 and 24.13 < x ≤ 32.82
