1. We saw in lecture that the arithmetic formula
   

   h(t) = 102 - t
   

   can be translated into Java as
   

   int h( int t ) { return 102 - t; }

   Translate the arithmetic formula g(n) = 3·n + 2 into Java
2. Without a calculator: What is 20% of of 60?                 
3. An airline charges extra for particularly heavy suitcases: $1 extra for each pound over 40 pounds. What should a flight attendent mo answer, when asked what the surcharge is for the following weights?

   	weight		surcharge
   mo.surcharge(	40	) =
   mo.surcharge(	41	) =
   mo.surcharge(	42	) =
   mo.surcharge(	50	) =
   mo.surcharge(	53	) =
   surcharge(	w	) =

   Note that the last entry is the difficult one: will be an arithmetic formula involving w. You can double check that if w is 40, your formula gives the same answer as you listed in the first row.
