问题如下：
Company A is in the automotive industry. If 10 million units were produced, each unit is expected to be sold at $600. Variable costs are $260 per unit and fixed costs are $2 billion. Which of the following is most likely to be true?
选项：
A.Company A would have less operating leverage if fixed production costs were greater than $2 billion.
B.Company A would generate positive operating income if unit sales were 3 million.
C.Company A would generate 24.3% more operating income if unit sales were 10% greater than 10 million.
解释：
C is correct.
$$ \begin{array}{l}DOL=\frac{{(10million)}{(\$600-\$260)}}{{\lbrack{(10million)}{(\$600-\$)}\rbrack}-\$2billion}\\=2.43.\end{array} $$
Company A would generate 24.3% more operating income if unit sales were 10% greater than 10 million.
请问C是怎么计算的呢？答案是乱码。谢谢！
