Answer: Our equation becomes,


y=22x\ ;\ x\leq 40\\\\and\\\\y=29(x+40)\ ;\ x>40

Explanation:

Let the number of hours she works for be 'x'.

Let the number of dollars she will be paid in week be 'y'.

Cost per hour for first 40 hours = $22

Cost per hour for over 40 hours = $29

We need to model the piece-wise equation for her total pay in week.

So, our equation becomes,


y=22x\ ;\ x\leq 40\\\\and\\\\y=29(x+40)\ ;\ x>40
