Lisa generally drinks milk per day = 60 ml.
When, She chases mice she drinks milk one-third more than usual.
So, she drinks = (60 + 1/3 * 60) ml.
= 60 + 20 = 80 ml.
In two weeks, there are 14 days.
And, she chased mice on every second day.
➡️ So, the days she chased mice are
2,4,6,8,10,12 and 14.
Total 7 days .⬅️
➡️ Days she didn't chase mice
= (14 - 7) = 7 days. ⬅️
Thus, during the past two weeks she drank milk
= 7 * 80 + 7 * 60 ml.
= 560 + 420 ml.
= 980 ml.
➡️ Hence, during the past two weeks, she drank 980 ml of milk.
