If an item that originally cost $20 is increased to $27, what is the percentage of increase in the item?

135%

Step-by-step explanation:

35% increase

Step-by-step explanation:

27-20=7

7/20=0.35

-7.692%

Buying: total cost
Total cost= commission + (price per share* # of shares ) ;
Total cost= 12 + (11.06*750)= 12+8295 = $8,307
Net gain or loss;
First, find cash received from sale of stock and deduct commission;
Cash from sale =10.24 * 750= 7,680
deduct commission= 7680-12= $7,668
Gain or loss= sale-cost = 7668-8307 = -$639, meaning there is a loss.
Annual rate of return= (net gain or loss/amount paid)*100%
return= -639/(8307)*100 = -7.692%
