John works a job that offers performance bonuses.  He makes $80 a day and works for 8 hours.  He has the option of working hard to earn the performance bonus of an extra $20 a day, but the extra effort results in a 2-hour longer workday.  How much does John make per hour if he decides to earn the bonus?
First, we need to determine the length of John's workday if he decides to earn the bonus. We do this by performing 8+2= <<8+2=10>>10 hours for his workday.
Next, we need to determine his overall pay. We do this by performing 80+20=<<80+20=100>>100 dollars a day.
We then determine John's hourly rate by dividing his pay by the number of hours worked, performing 100/10= <<100/10=10>>10 dollars an hour.
