5/9 s got 4 each
(1/3)(4/9) s = 4/27 s got 3 each
s - 5/9 s - 4/27 s =(27 -15 -4)/27 = 8/27 s got 2 each
so
264 = 4(5/9)s + 3 (4/27) s + 2(8/27) s
264 = (1/27)s (60+12 +16)
7128 = 88 s
s = 81
(1/3)(4/9) s = 4/27 s got 3 each
s - 5/9 s - 4/27 s =(27 -15 -4)/27 = 8/27 s got 2 each
so
264 = 4(5/9)s + 3 (4/27) s + 2(8/27) s
264 = (1/27)s (60+12 +16)
7128 = 88 s
s = 81
