The weight he lost was 3 pounds short of his targeted loss. Therefore
1/3(W-G) + 3 + 2/9(W-G) + 2 + 4/27(W-G) + 4/3 = (W-G) - 3
(9/27 + 6/27 + 4/27)(W-G) + 19/3 = (W-G) - 3
(19/27)(W-G) + 19/3 = (W-G) - 3
28/3 = (8/27)(W-G)
63/2 = (W-G)
So, his goal was to lose 21.5 pounds.
He fell 3 pounds short, so, he lost 18.5 pounds.
