Final answer:
To determine whether a salary falls within the range, use the inequality B. |x - 39,800| < 1,300. The range of starting salaries at the company is from $38,500 to $41,100.
Step-by-step explanation:
To determine whether a salary falls within the range of $39,800 plus or minus $1,300, we can use the inequality |x - 39,800| < 1,300. Here's how it works.
If we subtract 39,800 from the salary, we'll get the difference between the salary and the average starting salary.
By taking the absolute value of this difference, we can ignore the sign and focus on the magnitude. If the absolute difference is less than 1,300, then the salary falls within the range.
The range of starting salaries at the company is from $38,500 to $41,100.
This means that any salary that is between $38,500 and $41,100 (inclusive) is within the range.
