Step-by-step explanation:
=3x (2x+7)+2(2x+7)
=6x2+21x+4x+14
6x2+25x +14
 
        
             
        
        
        
You have that:
 - Her contribution from her salary <span>to her 401(k) plan, </span>is: 12%.
 - Her annual salary is: $55,700.
 Then, to solve this problem and calculate her pretax income, you must following the steps below:
 1. You must calculate the amount that Violet contributed to her 401(k) plan. So, you have:
 12%/100=0.12
 ($55,700x0.12)=$6,684 
 2. Now, you must subtract her annual pay ($55,700) by the amount obtained ($6,684), as below:
 Pretax income= $55,700-$6,684
<span> Pretax income=$49,016
</span><span>
 What is her pretax income?
 The answer is: Her pretax income is </span>$49,016
