A broker invested her own money in the stock market. During the first year, she increased her stock market wealth by 60 percent. In the second year, largely as a result of a slump in the stock market, she suffered a 30 percent decrease in the value of her stock investments. What was the net increase or decrease on her overall stock investment wealth by the end of the second year?
Select the correct option:	A) −5%	B) 5%	C) 12%	D) 20%	E) 80%
The actual answer is obtained by multiplying 160% by 70% and subtracting 100% from this total. That is: 160% × 70% = 112%; 112% − 100% = 12%.   Answer: 12%
