**DrBob222**, Monday, October 24, 2011 at 11:33pmI would do that this way.

Let X = candy from 3rd party.

(X/2)-3 = 5

Solve for X and I get 16 as follows:

Multiply through by 2

X-6=10 and X = 16 which means the boy had 16 going into the 3rd "robber."

How many into the second?

(X/2)-2 = 16

X-4=16

X = 4=32

X = 36 going into the second.

(X/2)-1 = 36

X-2=72

X = 74 to start.

Check it.

1/2 of 74 = 37 and 37-1=36

1/2 of 36 = 18 and 18-2 = 16

1/2 of 16 = 8 and 8-3=5.
