When working, you earn $12 per hour plus a $25 bonus.
1. Write an equation to find the total amount you earn (y) in (x) hours.
2. Find the inverse function
3. What does the inverse function calculate?
1. y = 12x + 25
2. y = (x-25)/12
3. It tells you the number of hours you worked if you know how much you earned
