I  know  a  few

a.    t =   200  +  3h

b .       Since  we  don't  know  the  flat fee, the   total  cost  is   t  = 6h

c.     We  can solve this

200  +  3h  <  6h

200 < 3h

h  >   200 / 3     =   about  67  hours

d.   Average  cost  per  hour  (at  the tennis club)  =    (200 + 3h)  / h

Here's  the graph  (I've substituted  x  for  h, but it's the same  graph )
