So the answer would be A. I had a bit of trouble figuring this out, but then I went to Order of Operations and found it out.
So you fill in n, and I just used 9 since it's in the question. So then, subtract 1 from 9, giving you 8. Then you multiply 0.35 by 8, giving you 2.8. Now lastly, add 7.51, and you get 10.31
