Here Let;
Appleton’s population =A
Berryville’s population = B
From the statemnent we can write as: A = 400 + B
and A = 3 * (B - 900) (SInce population of Berryville’s is reduced by 900)
or we can write as : 400 + B = 3 * (B - 900) (Since A = 400 + B )
Solving we get B= \(\frac{3100}{2}\) = 1550 which is Berryville’s population
