Luisa has 8 chapters of a book left to read. if she reads 2/3 of a chapter a day, how many days will it take her to finish the book?

8/ (2/3)= 12
 It will take Luisa 12 days to finish the book.

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.
