Answer:
9321
Explanation:
We can simply make a ratio (fraction) to solve this. Let total number of NO votes be N. Shown below is the ratio:

Now we can cross multiply and solve for N:

Hence, number of NO votes is 5736.
To get TOTAL number of votes, we add number of yes votes (3585) to that of number of no votes (5736).
Total votes = 3585 + 5736 = 9321
