The best prediction for the number of regular spectators that the program will have in 6 years is obtained with the following formula:
Pf = Po×(1-b) ^ t
Where:
Pf = final population
Po = initial population
b = decrease rate
t = timpo in years
So:
Pf = 223.00×(1-0.047) ^ 6
Pf = 167,056
The answer is the last option.
To solve this problem you must apply the proccedure shown below:
The linear functions have the form y=mx+b
where m is the slope and b is the y- intercept
Therefore, you have:
1) The slope -6/5 and b=(0,8) is:
y=(6/5)x+8
2) You have 3x-2y=1. Then, you only have to clear y:
y=(3/2)x-1/2

I would say the correct answer is D.
It corresponds with the statement made in the question, saying that 95%(the majority) of customers who rated the store as having high quality service returned.
The solutions to the given quadratic equation can be determined using quadratic formula.
b =coefficient of x term = -1
a = coefficient of squared term = 4
c = constant term = 9
Using the values in the above formula we get:
So, option D gives the correct answers
