castortr0y [4]

Answer:

Extra 4 cups to make up 11 cups a day

Step-by-step explanation:

Here we have that Jan obtains 15% of her fluid needs from food, therefore, she gets the remaining 85 % from drinking water

If the recommended daily intake = 2.7 liters or 91.3 oz

And she already consumes 48 oz of water and 16 oz of milk

Note milk is equivalent to 0.87 water therefore total intake = 48 + 16*0.87= 61.92 oz

She needs to take additional (91.3 - 61.92) = 29.4 oz or 3.68 ≈ 4 cups extra to meet her recommended daily dosage.
