For this month, Lily wants to finish reading twice as many books as she finished last month. If she finished reading 4 books last month, what will be the total number of books that she will finish for two months?
This month, Lily wants to finish reading 4 x 2 = <<4*2=8>>8 books.
So, for two months, she will finish reading 4 + 8 = <<4+8=12>>12 books.
