Question 16: The world population in 2010 was approximately 6.92 billion. The annual rate of increase was about 1.0235. Your friend wants to use x =
2055 to find the world population in 2065. Do you agree or disagree with
her and explain why

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.
