Question:

Devon earns $35 per hour for a regular 40-hour work week. Sometimes, he works over 40 hours a week and earns “double time” for the extra hours worked. (That means that his hourly rate for the additional hours over 40 hours per week is double his normal hourly rate.)

Part a)

If Devon works 48 hours in one week, how much would he earn that week? (Make sure you include units)

Part b)

Create a piecewise linear function to represent the amount Devon will earn in one week if he works xx hours.(Make sure to define your variables and use proper notation)

Part c)

What is the appropriate domain for this function? How do you know this?

Part d)

Graph this function in an appropriate window. (Make sure to label your axes, scale and any important points.)
