Answer: Lin needs to drink 27 ounces of water to reach her goal.
Step-by-step explanation: 1 cup = 8 fluid ounces.
8 cups = 8 x 8 = 64 ounces.
As of now Lin has drank 37 ounces of water. So, this means till now she has drank 37/8 = 4.625 cups of water.
In terms of ounces, she needs to drink 64-37=27 ounces of water to reach her goal.
Hence, the answer is 27 ounces or 8-4.625=3.375 cups.
