The strategy of using leverage to enhance investment returns:
选项：
A.amplifies gains but not losses.
B.doubles the net return if half of the invested capital is borrowed.
C.increases total investment return only if the return earned exceeds the borrowing cost.
解释：
C is correct. The use of leverage can increase an investor’s return if the total investment return earned on the leveraged investment exceeds the borrowing cost on debt. A is incorrect because leverage amplifies both gains and losses. B is
incorrect .
该怎么去分析它怎么错呢。如果忽略int rate，一半借的，net return rate确实是double.
