Alan, Terry and Mike have some marbles. Alan has 4 times as many marbles as Mike. Mike has 2/3 of the number of marbles Terry has. If Terry has 55 fewer marbles than Alan, how many marbles does each of them have?

Answer 1

a = 4m
m = 2/3 t
t = a-55
now solve as usual.

Answer 2

22 -> Mike
33 -> Terry
88 -> Alan
