Answer:
The bottle will last for 20 days.
Step-by-step explanation:
Given that:
Number of drops in a dose = 4 drops
Dose is taken three times a day, therefore,
Number of drops taken in a day = 4*3 = 12 drops
One milliliter = 20 drops
12 mL = 20*12 = 240 drops
Number of days the bottle will last can be find out by calculating total number of drops by the number of drops consumed in a day.
Number of days bottle will last = 
Hence,
The bottle will last for 20 days.
I believe the answer is 24.You do 12 divided by 3 and then you get 4. Then you do 4 times 6 and get 24.
What the composite function in the question is actually trying to explain is;
First of all, in the function
, we will find a result by writing
where we see the letter
.
We will write this result in the
function where we see the letter
and we will get the result.
That would be -0.4, my good sir.
