How do I get from Vijaywada to Amaravati without spending more than 200 rupees?

I am going to Amaravati for a few days and I can't find a good hotel there. But I found a good one in Vijayawada. Problem is, I have no idea how to get from Vijaywada to Amaravati by any means other than Uber which will drain my momey. So what should I do? If it helps, my hotel is situated near Vijaywada APSRTC bus depot (I think)
