    The salary is a one-time fixed amount. In this case it's unknown; let's call it s. The commission is paid out per unit sold. Let's call it c. If he sells 25 units, he makes 25c dollars in comminssion plus the fixed s dollars. In one week he earned $1200, so 25c + s = 1200 The other week, he sold 20 units earning 20c commission and earning a total salary of $1075, so 20c + s = 1075. We have: 25c + s = 1200 20c + s = 1075 If you solve this system of equations, you will know how much his fixed salary is and how much his commission is. Then you can write a function to find his weekly salary and comapre with the choices.
