A)
               Vf² = vi² + 2ad   Subtract 2ad from both sides
     Vf² - 2ad = vi²              Find the square roots of both sides
√(Vf² - 2ad) = √(vi²)         Cancel out the squares with the square roots
  Vf - √(2ad) = vi               Switch the sides to make it easier to read
                 vi = Vf - √(2ad)

B)                 Vf² = vi² + 2ad   Subtract vi² from both sides
             Vf² - vi² = 2ad           Divide both sides by 2a
    (Vf² - vi²) / 2a = d               Switch the sdies to make it easier to read
                         d = (Vf² - vi²) / 2a

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%
