Can you sell your game if it has DLC resource packs you purchased?

I am in the process of making a game and have strayed away from so of the DLC packs I have because I think I might actually attempt to sell this game.

Presumably you should be able to sell a game with DLC packs used since I did pay for them right? 

Anyhow I was just wanting to make sure I can sell my game using the DLC MUSIC and DLC GRAPHICS, which I can provide proof of purchase for.

Do I need to credit the original authors (which I am fine with)

-If I do need to how so? In the credits? A file in the game? Or what? 

Thank you so much for your time, and sorry for my ignorance of what should be basic knowledge. 

Yes, you can sell a game with DLC you paid for.

Yup. As long as payed for them your good to go.

All of our DLC come with a readme text that explains their terms of use, and how to credit. :)

Yes, you may use DLC you've purchased for commercial games made with RPG Maker. The artists who created said DLC do not require royalties. Credits are a must, and the crediting format is in the readme document. :)

Thank you so much for the fast response.

I purchased all my rpg maker stuff through STEAM so I will just go a digging for the files to make sure everyone is credited as such!
