问题如下：
Goodluck Company's revenue is $5000 in 2017, and cost of goods sold is $900 and depriciation is $700 in 2017, company has 3 times interest coverage ratio, please calculate the company's interest expenses in 2017:
选项：
A.$1,667
B.$1,133
C.$1,367
解释：
Answer is B.
Because of Interest coverage ratio = EBIT / I , so I=(5000-900-700)/3=1,333.
我问下，如果要不减 Dep，是叫 EBITDA，现在进一步减到了 Dep，所以叫 EBIT 是吧？
