Answer:
Step-by-step explanation:
8x - 6x + 12 = 3x - 18
2x + 12 = 3x - 18
-x + 12 = -18
-x = -30
x = 30
45/1.5 would give us
30 dosages total
The equation of Q(n) is 
<h3>How to determine the formula of Q(n)?</h3>
The functions are given as:


From the question, we understand that:
d = P(n)
This means that:
d = 88n + 23
Substitute d = 88n + 23 in R(d)

Also, from the question
Q(n) = R(n)
So, we have:

Hence, the equation of Q(n) is
