Answer:
One typical example of this linkage between the economy at the macroeconomic level, and business decisions at the macroeconomic and microeconomic level, is what happened with Lehman Brothers in 2008. 
Explanation:
Lehman Brothers was one of the main investment banks in the United States. During the years prior to the financial crisis, Lehman Brothers decided to pursue a risky but profitable strategy of over leveraging -lending a lot more money than they had as deposits. 
Once the financial crisis hit, a macroeconomic event, it affected the company at the macro and micro level. At the macro level because Lehman Brothers itself ceased to exist as it went bankrupt, and at the micro level, because it had to enter a process to pay off some debtors, and some of the employees who were laid off due to the dissolution of the firm.

Answer:
137.77%
Explanation:
obviously the numbers are missing, so I looked for a similar question:
"A stock that sold for $26 per share at the beginning of the year was selling for $52 at the end of the year. If the stock paid a dividend of $9.82 per share, what is the simple interest rate on the investment in this stock? Consider the interest to be the increase in value plus the dividend."
- total interest received (your gain) = (year end market value - purchase price) + dividends received = ($52 - $26) + $9.82 = $35.82
- initial investment (purchase price) = $26
simple interest rate of return on investment = total interest received / initial investment = $35.82 / $26 = 1.3777 or 137.77%
