Answer 1

Mark charges $10.hour. Rick charges $8.89.hour. Steve charges $9.38/hour. Andy charges $12/hour. The best deal is to take tennis lessons from Rick.

So Rick would be the choice

Answer 2

So,

Mark wants $100 for 10 hrs., or $10/hr.

Rick wants $80 for 9 hrs., or
`(80)/(9) /hr. or` $8.89/hr.

Steve wants $75 for 8 hrs., or $
`(75)/(8)` /hr. or $9.38/hr.

Finally, Andy wants $60 for 5 hrs., or $12/hr.

We can see that Rick offers the best deal, at $8.89/hr.
