**i don't need this to be written for me, i just need a few short answers to the following to get me going:

• Justify whether or not you would invest in this company.
• Incorporate the computations you performed to rationalize your decision.

Below are my calculations:

• Earnings per share 550,000-18000/200000=$2.66

• Book value per share of common stock 6500000-200000/200000=$31.5

• Price-earnings ratio 28/2.66=$10.53

• Dividend yield 1.50/28=5.36
