Anit [1.1K]

Answer:

1600 ml.

Step-by-step explanation:

Let x represent amount of tube-feeding formula.

We have been given that a tube feeding formula contains 6 grams of protein per each 80 ml of the formula.

To solve our given problem, we will use proportions as:

$\frac{x}{\text{120 gram}}=\frac{\text{80 ml}}{\text{ 6 grams}}$

$\frac{x}{\text{120 gram}}*\text{120 gram}=\frac{\text{80 ml}}{\text{ 6 grams}}*\text{120 gram}$

$x=\text{80 ml}*20$

$x=\text{1600 ml}$

Therefore, the patient should get 1600 ml of tube feeding formula every day.
