Part 1
Two of the most expensive cars in the world are car A and car B. The prices of these two cars differ by more than ​$10 comma 000. The price of car A is ​$131 comma 545.
a. Assuming that you do not know which model is more​ expensive, write an absolute value inequality that describes this situation. Use x for the price of car B.
b. What are the possibilities for the price of car​ B?

Answer 1

To tackle this problem, let's break it down step by step.

### Part 1a

We know the following:
- The price of car A is $131,545.
- The price difference between car A and car B is more than $10,000.

This leads us to write an absolute value inequality. The absolute value inequality that represents the situation can be set up as follows:

\[
|x - 131,545| > 10,000
\]

Here, \( x \) represents the price of car B.

### Part 1b

To find the possibilities for the price of car B, we will solve the inequality \( |x - 131,545| > 10,000 \).

This inequality means that the price of car B (x) must either be more than $10,000 greater than the price of car A or more than $10,000 less than the price of car A.

1. **Case 1:**
\[
x - 131,545 > 10,000
\]
\[
x > 141,545
\]

2. **Case 2:**
\[
x - 131,545 < -10,000
\]
\[
x < 121,545
\]

### Conclusion

Therefore, the possibilities for the price of car B \( x \) are:

\[
x < 121,545 \quad \text{or} \quad x > 141,545
\]

In summary:
- The price of car B can be less than $121,545 or more than $141,545.
