Nora had already read thirty percent of the book before he teacher assigned it to the class she is choosing between two options. option1: read 25%of the remaining pages each night or option2: read 28pages each night

Choosing option 1 will take 3 nights.

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.
