How do I calculate if I'm able to achieve an A in a cl?

So I got an 89% for my first midterm, which is 40% of my grade in cl, then i got and 88.5% in my second midterm, which is another 40% of my grade, and then my final is 20%, I was wondering if it was possible to still get an A in this cl? and if it is possible, what do I have to get on my final to achieve it?
