I don't quite understand the meaning of "A" when it comes to this problem. I'm assuming that "A" is the amount of interest paid within 3 years? But that's how I solved it. Because the equation is (I) over PT=
I = interest paid monthly/annually or whatever the determined number is.
P = principle (the money that was started out)
T = the time of the accruement
R= the interest rate.
That's why I'm assuming that A is going to equal I in this problem.
So it will be
188.80 over (/) 160 x 3= R
We will multiply 160 x 3 = 480
Then, we'll divide 188.80 by 480
188.80 ÷ 480 = 0.393.
We'll multiply that number by 100.
0.393 x 100 = 39.3%.
That's a HUGE interest rate, so that's why I'm not sure if A if the correct answer.

x = 16.22
x = 16.22 ÷ 3 = 16.22 × 
= 4.9907 ≈ 5
x = 5
Verification: 3 × 5 = 16.25 ≈ 16.22

The answer is Mean:
(took this from a different source) : <span>The mean is the most common measure of central tendency used by researchers and people in all kinds of professions. It is the measure of central tendency that is also referred to as the average. A researcher can use the mean to describe the data distribution of variables measured as intervals or ratios.
Hope this helped!
