Answer:
The cost of Ningbo Shipping Preferred stock is 12.40%
Step-by-step explanation:
In this question, we are asked to calculate the cost of Ningbo shipping Preferred stock.
To calculate this, we make use of the following mathematical relation;
The cost preferred stock Kp = Annual dividends/ Issued price-Cost of Issuing
From the question, we identify the following;
Issued price = $125
Annual dividend = $15
Cost of Issuing = $4
Inserting these into the formula we have;
Kp = $15/$125 - $4 = 12.40%
This means that Cost of Ningbo shipping preferred stock is 12.40%
If a quadratic equation has solutions 
and 
, then we can write it as
So, in your case, we have (let me write 1.5 as 3/2 and -0.25 as -1/4)
If we don't want decimal coefficient, we can multiply the whole expression by 8:
