John needs 13 bottles of water from the store. john can only carry 3 at a time. what's the minimum number of trips john needs to make to the store?

The minimum amount of trips would be 5. This is because in one trip he can only carry 3, so you would take 5 times 3. You may think it should be 4 trips, but 12 is 1 short of 13,so you would have to make one extra trip to get all 13 bottles.
