What was the question for this implicit rationale, and corresponding answer?
Since Rick and Jose's lunch cost was the same, Adam spent 2 / 3 * 45 = $30 on his lunch. The three friends ate food worth 30 + 45 + 45 = $120.
 The answer: 120
The question: After working out for 3 hours, three friends go out for lunch. Adam spends two-thirds as much money on lunch as Rick. Rick and Jose eat lunch of the same price. If Jose ate lunch worth $45, what is the cost of lunch for all three?
