[求助]关于profitable的疑问

看到有人说

The logic point ETS often intends to evaluate the testers remains, profits = volume X unit price. Of course, the profit does not contain the meaning of the difference between the revenue and cost.

请问profitable到底要不要考虑cost呢？现在不是ETS出题。。这方面有没有变化呢？。。

因为还蛮经常遇到问more profitable的问题,这点还蛮关键的
