Imac burn music cd

I am using an iMac 27inch circa 2015 that was given to me by my grandson. After buying songs on itunes I wanted to put them on a cd for my car. Imagine my surprise when I noticed there was no slot where I could insert a blank cd! Could someone give me an idea as to how I could transfer my music to a cd? Am I making any sense? I don't have anyone nearby that can help me with this. Any suggestions greatly appreciated.
