If Lilit and Sergio each sell 3 candles per day, then over the next 2 days, each of them will sell a total of:
- 3 candles/day * 2 days = 6 candles for each person.
Now, if we consider the ordered pairs representing the number of candles sold by Lilit and Sergio, we denote the number of candles sold by Lilit as \( L \) and the number of candles sold by Sergio as \( S \).
The possible ordered pairs for the candles sold can be:
- \( (6, 6) \): Lilit sold 6 candles, Sergio sold 6 candles.
- \( (6, 0) \): Lilit sold 6 candles, Sergio sold 0 candles.
- \( (0, 6) \): Lilit sold 0 candles, Sergio sold 6 candles.
- \( (3, 3) \): Lilit sold 3 candles, Sergio sold 3 candles, which doesn't match the criteria since they sell 3 candles each day for 2 days.
- \( (0, 0) \): They sold no candles at all, which is also not relevant here.
From this logic, the only relevant ordered pair that represents the situation where both sold exactly 6 candles each over the span of two days is \( (6, 6) \).
If you have any specific pairs provided for selection, please list them, and I can help identify which ones fit the criteria.
