Answer:
The EAR on the investment is 23.79%
Explanation:
Here, we are concerned with calculating the EAR on the stock investment.
Firstly, we start with calculating the return on shares
Mathematically, that is; P1 - P0
From the question P1 = $57.36 while P0 = $54.14
So Return on shares = $57.36-$54.14 = $3.22
We proceed with calculating the Return on shares in percentage 
Mathematically;
Return on shares in % = Return on shares/P0 * 100
= 3.22/54.14 * 100 = 5.95%
Lastly we calculate the effective annual interest;
The effective annual interest = 5.95%/3 * 12 = 23.79%
