Formal:
* 是的,我能,您呢? (Shì de, wǒ néng, nín ne?) This is a very polite and formal way to say it.
* 可以,我可以,您呢? (Kěyǐ, wǒ kěyǐ, nín ne?) This is another formal option, meaning "I can, you?"
Informal:
* 对,我能,你呢? (Duì, wǒ néng, nǐ ne?) This is a casual way to say it.
* 能,我能,你呢? (Néng, wǒ néng, nǐ ne?) This is another casual option.
Note: The "are you?" part at the end is translated as "您呢?" (nín ne?) for formal situations and "你呢?" (nǐ ne?) for informal situations.
The choice of which translation to use depends on the context of the conversation and the relationship between the speakers.
