The number of people estimated to vote in an election was 7,000. The actual number of people who voted was 5,600. By what percent did the estimate vary from actual turnout?

%

In the previous election 6,400 people voted. What is the percent decrease in actual voters?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
