A broker invested her own money in the stock market. During the first year, she increased her stock market wealth by 40 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?
Answers:	A) −5%	B) −2%	C) 15%	D) 20%	E) 80%
The actual answer is obtained by multiplying 140% by 70% and subtracting 100% from this total. That is: 140% × 70% = 98%; 98% − 100% = -2%.   Answer: −2%
