Answer:
$520.75
Step-by-step explanation:
We need to take into account the equation which determines Robin's yearly bonus.
-0.625x+532
Then, we will substitute 18 for x because x represents the number of complaints.
-0.625(18)+532
Now, this problem is set up in a hard to understand manner, so let's simplify it. Basically, for every complaint Robin receives, her bonus is deducted by $0.625. This is evidenced by the fact that the 0.625 is negative. The next step would be to multiply 18 by -0.625 to find the amount of money lost.
-11.25+532
Adding a negative is the same as subtracting a positive, allowing us to rearrange this.
532-11.25
520.75
There's the answer.
