The first set of 5 answers that you typed do not answer the question that you typed immediately above them. In the second set of 5 answers that you typed, the desired answer is the 4th one, but you left out the "sec" after the "3600" Third set: the number of people who voted yes was 363. 363/525 = 0.6914, best answer is 69.1% Fourth set: You've mismatched the question with the answer set. The answer should be about 65, and none of these answers is anywhere near that. Fifth set: $5.25 = 0.15 times x x = $5.25/0.15 = $35, the last answer in the set.
