What was the question for this implicit rationale, and corresponding answer?
Steve weighs 110 - 8 = 102 pounds. Stan weighs 102 + 5 = 107 pounds. Their total weight is 102 + 107 + 110 = 319 pounds.
 The answer: 319
The question: Stan weighs 5 more pounds than Steve. Steve is eight pounds lighter than Jim. If Jim weighs 110 pounds and the three of them crowd onto a scale at the same time, what is their total weight?
