Appleton’s population is 400 greater than Berryville’s population. If Berryville’s population were reduced by 900 people, then Appleton’s population would be 3 times as large as Berryville’s population. What is Berryville’s current population?
A 1550
B 1650
C 1750
D 1850
E 1950
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
