2. At a certain high school, the respective weights for the following subjects are: Mathematics 3, English 3, History 2, Science 2 and Art 1. What is a student's average whose marks were the following: Geometry 89, American Literature 92, American History 94, Biology 81, and Sculpture 85?
A. 85.7 B. 87.8 C. 88.9
D. 89.4 E. 90.2

I said E but I got it wrong, when I checked the answer it said to add all the numbers up and divide by 11 but I have no idea where they got the 11 from. How did they get to divide by 11? Maybe I am missing something?
