Re: Population math help!

In a message dated 99-02-15 15:49:18 EST, you write:

<< there must be an easier way of doing this than repeating (X x Y) + Z
 a number of times equal to Q. (I'm positing a 97-year old colony. You
can
 understand my desire to find an easier way.) You can't just do
 q{(xy)+z}, because (xy) is a constantly increasing number.
 
 Please help... >>
run the attached file in Qbasic, enter the numbers and hit enter.
INPUT "Colony Age", Q
INPUT "Initial Pop", X
INPUT "Anerage Annuel Groth", Y
INPUT "Average Annual Immigration", Z
Pop = X
FOR a = 1 TO Q
  Pop = (X * (.01 * Y)) + Z + Pop
NEXT a
PRINT Pop
