Answer 1

Answer: Joel collects 1,100 empty cans

Explanation:

Ryan=550

Anne=550/2=275

method 1 : method 2 :

550+275=825 joel has twice as many cans as ryan

1925-825=1100 ryan=550

550x2=1100

Answer 2

A + R + J = 1925
A = 1/2R
J = 2R

1/2R + R + 2R = 1925
7/2R = 1925
R = 550

J = 2(550)
J = 1100

Joel collects 1100 cans.
