Asalesperson makes a base salary of $2100 per month. once he reaches $42,000 in total sales, he earns an additional 5% commission on the amount in sales over $42,000.
(1) graph the function.
(2) if the salesperson had $80,000 in sales, how much was his salary?
(3) if the salesperson's total salary for a month was $4500, how much were his total sales for that month?
(4) compute s(25000) and interpret what this means in the context of the problem.

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:

The graph of the function is shown in the attached image.

(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.
