How many ounces of coffee does John drink every 4 days? ** He drinks 128/2 = <<128/2=64>>64 ounces of coffee every 4 days
How many ounces of coffee does John drink a day? ** That means he drinks 64/4 = <<64/4=16>>16 ounces of coffee a day
How many cups of coffee does John drink a day? ** So he drinks 16/8 = <<16/8=2>>2 cups a day
