Answer:

35 days

Explanation:

Andrew brings juice for lunch every 5 days and Hannah brings juice every 7 days

Find the lowest common multiple of 5 and 7

Andrew (every 5 days) = 10, 15, 20, 25, 30, 35, 40, 45, 50

Hannah (every 7 days) = 14, 21, 28, 35, 42, 49, 56

The lowest common multiple of 5 and 7 is 35

Therefore, if Andrew and Hannah both brought juice today, it will take 35 days before they will both bring food again on the same day.
