Answer:
A shipment of 150 bottles will weigh 120 pounds.
Step-by-step explanation:
Given that:
24 bottles of water weigh 30 pounds
Ratio of bottles to weight = 24 : 30
Number of bottles in shipment = 150
Weight of bottles = x
Ratio = x : 150
As the relation is proportional
24 : 30 :: x : 150
Product of mean = Product of extreme
30x = 24 * 150
30x = 3600
Dividing both sides by 30

Hence,
A shipment of 150 bottles will weigh 120 pounds.
30b because 2 time 3 is 6 and 6 times 5 is 30 so its 30b
It is the first one, so where it is marked is already correct
