To find the weight of 90 empty water bottles, we first need to determine the weight of one bottle. If 150 bottles weigh 4.5 pounds, we can divide 4.5 by 150 to find the weight of a single bottle. That's 0.03 pounds per bottle! Now, multiplying that by 90 gives us a total weight of approximately 2.7 pounds for 90 bottles.
