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