Question: John buys 1/2 gallon jugs of cold brew coffee every 4 days.  How many cups of coffee does he drink a day? Is final answer 2?
Answer: He drinks 128/2 = <<128/2=64>>64 ounces of coffee every 4 days
That means he drinks 64/4 = <<64/4=16>>16 ounces of coffee a day
So he drinks 16/8 = <<16/8=2>>2 cups a day
