I get the feeling you're overthinking it a bit.  Take a step back and try to put things into an equation.  Take for example the first problem.  You have 20 haircuts in 7 hours.  The total amount of hours worked is 35 hours.  Now think, how many 7 hour periods are there in 35 hours?  When you know how many that is, simply find out how many haircuts are done in that span of time.  The unit price is up to you.
