Say that a program's execution time behavior can be
expressed by

         3
t = A * N

where t is the execution time, A is some constant, and N
is the number of data objects dealt with.

If the program takes 2 seconds to deal with 200 objects,
how much time should it take to deal with 400 objects?


------------------------

Say that we run a program for several different amounts
of data (represented by N) and get the following timing
results:

N	t
-----------
100	04 s
200	16 s
300	36 s
400	64 s

Complete the formula below that describes the execution
time behavior.

	t = A *______

What will the value of A be for the data given?  ______

Say that we run a program for several different amounts
of data (represented by N) and get the following timing
results:
N	t
-----------
100	 4 s
200	 7 s
400	10 s
800	13 s

Complete the formula below that describes the execution
time behavior.

	t = A *______
