is this a real question? Your grammar is so poor I can't even decipher an equation.
A lot. Liliana runs a lot of laps. How many laps Liliana runs on Saturday is directly equivalent to how much she drank, or "used", on the previous Friday night. But even if she doesn't run laps on Saturday, it wouldn't matter because she's run so many laps on the preceding days of the week and, assuming by her precise count of the laps she runs each day, Liliana will probably run enough laps to make up for Saturday on the following days of the week.
