Answer 1

Answer:

i stop there i hope it at least help

Step-by-step explanation:

start group A: x = 100

start group B: y = 25

every 4 years: A = 2x

every 3 years: B = 2y

going from 2001 to 2012 -> 11 years

11 years = 132 months

4 years = 47 months

3 years = 36 months

11 / 4 = 2x3/4 = 2.75  -> doubles two times

11 / 3 = 3x2/3 = 3.6  -> doubles three times

A: 2 x (2 x 100) = 400

B: 2 x [2 x (2 x 25)] = 200
