Loris needs three more books to have the same number as Lamont, who has twice the number of books Darryl has. If Darryl has 20 books, calculate the total number of books the three have.
Since Darryl has 20 books, Lamont, who has twice the number of books Darryl has, has 20*2 = <<20*2=40>>40 books.
The total number of books both Darryl and Lamont has is 40+20 = <<40+20=60>>60 books.
To have the same number of books as Lamont, Loris needs 3 more books, meaning she has 40-3 = <<40-3=37>>37 books.
In total, the three has 60+37= <<60+37=97>>97 books
