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

Answer:
Step-by-step explanation:
Step 1: Calculate the mean.
Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations.
Step 3: Add those deviations together.
Step 4: Divide the sum by the number of data points.
