Relevant information
Fact
One pint is the same as 16 fluid ounces.
Plan
Calculate the total number of bottles the factory can produce in 12 hours. Then, convert the total number of bottles to the total number of fluid ounces. Lastly, convert fluid ounces to pints.
Solution
If then factory can produce 225 bottes in one hour, then, in 12 hours, 225*12=2700 bottles are produced. Since each bottle is 24 fluid ounces, then the factory produced 2700*24=64800 fluid ounces in total. Converting this to pints, the factory produced 64800/16=4050 pints
