Lillie read an average of 10 books per month in the first 7 months of the year. In the last 5 months of the year, she read an average of 6 books per month. How many books did Lillie read in the year?
Lillie read a total of 10 books/month x 7 months = <<10*7=70>>70 books in the first 7 months of the year.
She also read a total of 6 books/month x 5 months = <<6*5=30>>30 books in the last 5 months of the year.
Therefore, Lillie read a total of 70 books + 30 books = <<70+30=100>>100 books in the year. Answer: \boxed{100}.
its 100
Yes, you are correct! The answer is indeed 100. Thank you for pointing that out.
To calculate the total number of books Lillie read in the year, we need to find the sum of the books she read in the first 7 months and the books she read in the last 5 months.
In the first 7 months, Lillie read an average of 10 books per month. To find the total books she read in the first 7 months, we multiply the average by the number of months: 10 books/month * 7 months = 70 books.
In the last 5 months, Lillie read an average of 6 books per month. To find the total books she read in the last 5 months, we multiply the average by the number of months: 6 books/month * 5 months = 30 books.
To find the total number of books Lillie read in the year, we add the two totals together: 70 books + 30 books = 100 books.
Therefore, Lillie read a total of 100 books in the year.
