Question

Appletons population is 400 greater than berryvilles population. if berryvilles population were reduced by 900 people, then appletons population would be 3 times as large as berryvilles population. what is berryvilles current population?

Answer 1

Answer:

575

Step-by-step explanation:

let Appleton's population be x

and berryviles population be y

so firstly

x=400+y

also 3(900-y)=x

so 400+y=2700-3y

3y+y=2700-400

4y=2300

y=575
