The Amex company decides to restructure its formula to calculate the monthly salary of its

sellers and establishes that if the monthly sales are less than $ 10,000.00 the seller will not have

salary, if they are greater than or equal to $ 10,000.00 but less than or equal to $ 20,000.00, then,

the salary will be $ 1,150.00 and, finally, if the sales are in excess of $ 20,000.00 the salary will be

$ 1,150.00 and 5% of the excess. Define the salary function. What will be the salary of a salesperson who

reaches a sales volume of $ 18,750.00? What will be the salary of a salesperson who reaches a

sales volume of $ 68,350.00? If the salary of a salesperson last month was $ 3,750.00; to

how much did your sales go up? Sketch the segment graph of the wage function by parts.
