Homework Help: ALGEBRA

Posted by el chave del ocho on Thursday, February 23, 2012 at 8:08pm.

I went to the car show this weekend and that is what I saw: Every red car was a sport car, but I found it odd that half of all the blue were sports cars. A salesman told me that half of all the sports car were red. I counted 40 blue cars and 30 red cars. How many sports cars were neither blue nor red?
