Answer:

100 Books

Step-by-step explanation:

Step 1

The books that Lillie read in the first months = 10 books per month

The books that Lillie read in the first 7 months = 7 months * 10 books per month = 70 books in first 7 months

Step2

The books that Lillie read in the 8th month = 6 books per month

The books that Lillie read in the last 5 months = 5 months * 6 books per month = 30 books in last 5 months

Step 3

Total books read in a year = Books read in 7 months + Books read in 5 months

Total books read in a year = 70 books + 30 books = 100 books
