Answer: it will take more 3.75 days for her to finish the book.
Step-by-step explanation:
Let x represent the number of extra days that it will take her to finish the book.
Ericka's book is 675 pages long and she has read 375 pages so far. This means that the number of pages remaining for her to read would be
675 - 375 = 300
If Ericka reads 80 pages per day. It means that in x days, she would read 80x pages. Therefore,
80x = 300 = 3.75
