【单选题】In a certain conservative mutual fund, 70 percent of the money is invested in bonds, and of that portion, 40 percent is invested in highly rated corporate bonds. If at least $1.4 million in this fund is invested in highly rated corporate bonds, what is the smallest possible total value for the mutual fund
A、$4 million
B、$5 million
C、$6 million
D、$7 million
E、$8 million

网考网参考答案：B
网考网解析：
If 40 percent of the amount invested in bonds is invested in highly rated corporate bonds, then the total amount invested in bonds is $1.4 million times 10/4 = $3.5 million. $3.5 million in bonds is 70 percent of the total fund, so the total fund is $3.5 million times 10/7 = $5 million. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
