(4)
Step-by-step explanation:
(1) Let's call S the salary for the month the seller wins.
Let's call x the amount of dollars reached by the sales of that month.
The seller earns a base salary of $ 2100 per month.
Then, if x> 42,000 he wins a commission of 5% on sales.
Then the equation modeling this situation is:
<em>The graph of the function is shown in the attached image.
</em>
(2) If x = 80,000, then your salary was:
(3) If S was 4500 and we want to find x then we equal S to 4500 and solve for x.
(4) S (25000) means that x equals 25000. Since x represents sales, this means that during the month, the seller only reached $ 25,000.
Then
Therefore .
