Explanation:
a.)Buying: total cost
Total cost= commission + (price per share× Number of of shares ) ;
Total cost= 10 + (11.06×500)=$5540
b.)Net gain or loss;
First, find cash received from sale of stock and deduct commission;
Cash from sale =10×500= $ 5000
deduct commission= 5000-10= $4990
Gain or loss= sale-cost = 4990-5540 = -$550, meaning there is a loss.
c.) Annual rate of return= (net gain or loss/amount paid)×100%
return= -550/(5540)×100 = -9.92%
