Answer:
80 drops per minute
Explanation:
To find the number of drops per minute that Brandon needs to administer, we can use the following equation:

We know the total number of drops is 480 ml × 60 drops/ml = 28,800 drops.
We also know the total time in minutes is 6 hours × 60 minutes/hour = 360 minutes.
Substituting these values into the equation, we get:


Therefore, Brandon needs to administer 80 drops per minute of IV fluid.
