anne, ryan and joel collect empty cans for recycling. they collect a total of 1925 cans. anne collects half as many cans as ryan. joel collects twice as many cans as ryan. how many cans does joel collect?

Answer 1

a+r+j = 1925

2a=r

j = 2r

a = 1/2r

3 1/2r = 1925

7/2 r = 1295

r = 370

j= 370*2 = 740

Answer 2

A+R+J=1925
A=R/2
J=2R
R/2+R+2R=1925
3.5R=1925
R=550
J=2*550

J=1100
