Hello! Okay, I can help give you the correct answer. So John has 13 bottles and can carry 3 at a time;

[] [] [] = 1 trip (3 bottles)
[] [] [] = 1 trip  (6)
[] [] []= 1 trip  (9)
[] [] [] = 1 trip (12)
[]= 1 trip (13)

John will need to take 5 trip to carry all the bottles.
This can help solve other problems like these type. Hope it helps!
