Tobramycin Eye Suspension, 1 drop into each eye 3 times daily, 10ml bottle. What is the day supply (20gtts/mL)…. Show work please
~~~~~~~~~~~~~~~~~~~~~~~~
The question is worded BOTH terribly and incorrectly.
A correct formulation is this " For how many days this supply will last ? "
I will solve the problem in this modified formulation.
1 drop =  milliliters, or 1 milliliter = 20 drops
(as given in the problem and is consistent
with the standard conversion factor).
So, 10 mL in the bottle are equivalent to 10*20 = 200 drops.
Thus, your supply in the bottle is 200 drops.
Every time you use 1 + 1 = 2 drops for (1+1) = 2 two/both your eyes.
So, you can treat your eyes 200 : 2 = 100 times.
Each treatment covers 8 hours.
100 treatments will cover 8*100 = 800 hours.
One day in this context is 24 hours.
So, the number of days is  = 33  .
Thus, one bottle supply is enough for full 33 days.
At the end of the 33-th day, you will make the last treatment,
and its action will continue (will last) first 8 hours on the day 34.
Solved.
