Answer:
A. $1,056,000 ≤ x ≤ $1,344,000
Step-by-step explanation:
The average annual salary of each of the 48 employees is given as;
$25,000
The total salary that the company pays to its employees annually is thus;
$25,000 * 48 = $1,200,000
Now, the total annual maximum variance of the employees salaries would be;
$3,000 * 48 = $144,000
The lower limit of the total salary that the company pays to its employees annually is calculated as;
$1,200,000 - $144,000 = $1056000
The upper limit of the total salary that the company pays to its employees annually is calculated as;
$1,200,000 + $144,000 = $1344000
Therefore, the range of the total salary that the company pays to its employees annually is;
$1,056,000 ≤ x ≤ $1,344,000
